Physical Activity The Secret to Good Health
Physical Activity The Secret to GoodHealthPhysical activity is often touted as the secret to good health, and for good reason. Engaging in regular physical activity has been linked to a myriad ofhealth benefits, including improved cardiovascular health, weight management, and mental well-being. However, despite the overwhelming evidence supporting the importance of physical activity, many people still struggle to incorporate it into their daily lives. This can be due to a variety of reasons, including lack of time, motivation, or access to resources. In this response, we will explore the significance of physical activity for good health from multiple perspectives, and offer practical solutions for overcoming common barriers to incorporating physical activity into one's lifestyle. From a biological perspective, the human body is designed for movement. Our muscles, bones, and cardiovascular system all thrive on regular physical activity. When we engage in physical activity, our heart rate increases, leading to improved circulation and oxygen delivery to our organs and tissues. This not only strengthens our cardiovascular system, but also reduces the risk of developing chronic conditions such as heart disease, stroke, and diabetes. Additionally, physical activity plays a crucial role in maintaining a healthy weight and preventing obesity, which is a significant risk factor for many health problems. From a biological standpoint, it is clear that physical activity is essential for good health. From a psychological perspective, physical activityhas been shown to have a profound impact on mental well-being. When we engage in physical activity, our bodies release endorphins, also known as "feel-good" hormones, which can help alleviate symptoms of stress, anxiety, and depression. Regular physical activity has also been linked to improved cognitive function anda reduced risk of developing neurodegenerative diseases such as Alzheimer's. Furthermore, participating in physical activity can boost self-esteem and confidence, as individuals experience a sense of accomplishment and mastery over their bodies. From a psychological standpoint, it is evident that physicalactivity is crucial for maintaining good mental health. From a social perspective, physical activity can serve as a means of connecting with others and building asense of community. Whether it's joining a sports team, participating in group fitness classes, or simply going for a walk with a friend, physical activity provides opportunities for social interaction and support. This can be especially beneficial for individuals who may feel isolated or lonely, as it offers a chance to form meaningful connections and foster a sense of belonging. Additionally, engaging in physical activity with others can provide a source of motivation and accountability, making it easier to stick to a regular exercise routine. From a social standpoint, physical activity is not only beneficial for individual health, but also for building relationships and strengthening communities. Despite the numerous benefits of physical activity, many people still struggle to make it a priority in their lives. One common barrier is lack of time. In today's fast-paced world, it can be challenging to carve out time for exercise amidst work, family responsibilities, and other commitments. However, it's important to recognize that physical activity doesn't have to be time-consuming or complicated. Even short bursts of activity throughout the day, such as taking the stairs instead of the elevator, going for a brisk walk during lunch break, or doing a quick home workout, can add up and make a significant impact on one's health. By reframing the way we think about physical activity and finding creative ways to incorporate it into our daily routines, lack of time can become less of a barrier. Another common barrier to physical activity is lack of motivation. It's normal to experience fluctuations in motivation, especially when it comes to engaging in activities that require physical exertion. One way to overcome this barrier is to find activities that are enjoyable and align with one's interests and preferences. Whether it's dancing, hiking, playing a sport, or practicing yoga, there are countless ways to be physically active, and finding something that brings joy and fulfillment can makeit easier to stay motivated. Setting realistic and achievable goals, tracking progress, and celebrating small victories along the way can also help maintain motivation and momentum. Additionally, seeking support from friends, family, or a fitness community can provide encouragement and accountability, making it easierto stay on track. Access to resources, such as facilities, equipment, and professional guidance, can also be a barrier to physical activity for some individuals. However, it's important to remember that physical activity doesn'tnecessarily require a gym membership or fancy equipment. There are plenty of activities that can be done with minimal or no equipment, such as bodyweight exercises, running, or cycling. Many communities also offer free or low-cost options for physical activity, such as public parks, walking trails, and community fitness programs. For those who may benefit from professional guidance, seeking out affordable options such as community centers, local fitness classes, or online resources can provide the support needed to get started. By exploring andutilizing the resources available, lack of access can be less of a barrier to engaging in physical activity. In conclusion, physical activity is indeed the secret to good health, offering a multitude of benefits for the body, mind, and spirit. From a biological perspective, it supports cardiovascular health, weight management, and overall well-being. From a psychological perspective, it promotes mental health, cognitive function, and self-esteem. From a social perspective, it fosters connections, support, and a sense of community. While there are common barriers to incorporating physical activity into one's lifestyle, such as lack of time, motivation, and access to resources, there are practical solutions that can help overcome these challenges. By reframing the way we think about physical activity, finding enjoyable and sustainable activities, and utilizing available resources, it is possible to make physical activity a priority and reap the many rewards it has to offer.。

Additionally, the rise of sedentary behaviors, such as prolonged sitting and increased screen time, has further contributed to a decline in physicalactivity levels across the population. To address these challenges, it is crucialto promote physical activity at both the individual and societal levels. Encouraging workplace wellness programs, creating safe and accessible environments for physical activity, and providing education about the importance of exercise are all essential components of promoting a more active lifestyle.

From reducing the risk of chronic diseases to improving mood and boosting energy levels, the importance of physical activity cannot be overstated. In this response, I will explore the various aspects of physical activity and its impact on overall health, drawing from scientific research and personal experiences. One of the most compelling reasons to prioritize physical activity is its ability to prevent and manage chronic diseases.

Taking the stairs instead of the elevator, parking further away from a destination, or even stretching during commercial breaks can all add up to significant health benefits over time. It is important to shift the focus from achieving a certain body image to prioritizing overall health and well-being. By reframing the concept of exercise as a means of self-care rather than a chore, individuals may be more inclined to incorporate physical activity into their lives.

Guidelines for Data Processing and Analysis of the International Physical Activity Questionnaire (IPAQ)– Short and Long FormsNovember 2005Contents1. Introduction2. Uses of IPAQ Instruments3. Summary Characteristics of Short and Long Forms4. Overview of Continuous and Categorical Analyses of IPAQ5. Protocol for Short Form6. Protocol for Long Form7. Data Processing Rules8. SummaryAlgorithmsAppendix 1. At A Glance IPAQ Scoring Protocol – Short Forms Appendix 2. At A Glance IPAQ Scoring Protocol – Long Forms1. IntroductionThis document describes recommended methods of scoring the data derived from the telephone / interview administered and self-administered IPAQ short and long form instruments. The methods outlined provide a revision to earlier scoring protocols for the IPAQ short form and provide for the first time a comparable scoring method for IPAQ long form. Latest versions of IPAQ instruments are available fromwww.ipaq.ki.se.Although there are many different ways to analyse physical activity data, to date there is no formal consensus on a ‘correct’ method for defining or describing levels of physical activity based on self–report population surveys. The use of different scoring protocols makes it very difficult to compare within and between countries, even when the same instrument has been used. Use of these scoring methods will enhance the comparability between surveys, provided identical sampling and survey methods have been used.2. Uses of IPAQ InstrumentsIPAQ short form is an instrument designed primarily for population surveillance of physical activity among adults. It has been developed and tested for use in adults (age range of 15-69 years) and until further development and testing is undertaken the use of IPAQ with older and younger age groups is not recommended.IPAQ short and long forms are sometimes being used as an evaluation tool in intervention studies, but this was not the intended purpose of IPAQ. Users should carefully note the range of domains and types of activities included in IPAQ before using it in this context. Use as an outcome measure in small scale intervention studies is not recommended.Characteristicsof IPAQ Short and Long Forms3. Summary1. IPAQ assesses physical activity undertaken across a comprehensive set ofdomains including:a. leisure time physical activityb. domestic and gardening (yard) activitiesc. work-related physical activityd. transport-related physical activity;2. Theshort form asks about three specific types of activity undertaken in IPAQthe four domains introduced above. The specific types of activity that areassessed are walking, moderate-intensity activities and vigorous-intensityactivities.3. The items in the short IPAQ form were structured to provide separate scores onwalking, moderate-intensity and vigorous-intensity activity. Computation of the total score for the short form requires summation of the duration (in minutes)and frequency (days) of walking, moderate-intensity and vigorous-intensityactivities. Domain specific estimates cannot be estimated.long form asks details about the specific types of activities IPAQ4. Theundertaken within each of the four domains. Examples include walking fortransportation and moderate-intensity leisure-time activity.5. The items in the long IPAQ form were structured to provide separate domainspecific scores for walking, moderate-intensity and vigorous-intensity activitywithin each of the work, transportation, domestic chores and gardening (yard) and leisure-time domains. Computation of the total scores for the long formrequires summation of the duration (in minutes) and frequency (days) for all the types of activities in all domains. Domain specific scores or activity specific sub-scores may be calculated. Domain specific scores require summation of thescores for walking, moderate-intensity and vigorous-intensity activities within the specific domain, whereas activity-specific scores require summation of thescores for the specific type of activity across domains.4. Overview of Continuous and Categorical Analyses of IPAQBoth categorical and continuous indicators of physical activity are possible from both IPAQ forms. However, given the non-normal distribution of energy expenditure in many populations, it is suggested that the continuous indicator be presented as median minutes/week or median MET–minutes/week rather than means (such as mean minutes/week or mean MET-minutes/week).4.1 ContinuousVariablesData collected with IPAQ can be reported as a continuous measure. One measure of the volume of activity can be computed by weighting each type of activity by its energy requirements defined in METs to yield a score in MET–minutes. METs are multiples of the resting metabolic rate and a MET-minute is computed by multiplying the MET score of an activity by the minutes performed. MET-minute scores are equivalent to kilocalories for a 60 kilogram person. Kilocalories may be computed from MET-minutes using the following equation: MET-min x (weight in kilograms/60 kilograms). MET-minutes/day or MET-minutes/week can be presented although the latter is more frequently used and is thus suggested.Details for the computation for summary variables from IPAQ short and long forms are detailed below. As there are no established thresholds for presenting MET-minutes, the IPAQ Research Committee propose that these data are reported as comparisons of median values and interquartile ranges for different populations.4.2 Categorical Variable: Rationale for Cut Point ValuesThere are three levels of physical activity proposed to classify populations:1. Low2. Moderate3. HighThe algorithms for the short and long forms are defined in more detail in Sections 5.3 and 6.3, respectively. Rules for data cleaning and processing prior to computing the algorithms appear in Section 7.Regular participation is a key concept included in current public health guidelines for physical activity.1 Therefore, both the total volume and the number of days/sessions are included in the IPAQ analysis algorithms.The criteria for these levels have been set taking into account that IPAQ asks questions in all domains of daily life, resulting in higher median MET-minutes estimates than would have been estimated from leisure-time participation alone. The criteria for these three levels are shown below.Given that measures such as IPAQ assess total physical activity in all domains, the “leisure time physical activity” based public health recommendation of 30 minutes on most days will be achieved by most adults in a population. Although widely accepted as a goal, in absolute terms 30 minutes of moderate-intensity activity is low and broadly equivalent to the background or basal levels of activity adult individuals would accumulate in a day. Therefore a new, higher cutpoint is needed to describe the levels of physical activity associated with health benefits for measures such as IPAQ, which report on a broad range of domains of physical activity.‘High’This category was developed to describe higher levels of participation. Although it is known that greater health benefits are associated with increased levels of activity there is no consensus on the exact amount of activity for maximal benefit. In the absence of any established criteria, the IPAQ Research Committee proposes a measure which equates to approximately at least one hour per day or more, of at least moderate-intensity activity above the basal level of physical activity Considering that basal activity may be considered to be equivalent to approximately 5000 steps per day, it is proposed that “high active” category be considered as those who move at least 12,500 steps per day, or the equivalent in moderate and vigorous activities. This represents at least an hour more moderate-intensity activity over and above the basal level of activity, or half an hour of vigorous-intensity activity over and above basal levels daily. These calculations were based on emerging results of pedometers studies.2This category provides a higher threshold of measures of total physical activity and is a useful mechanism to distinguish variation in population groups. Also it could be used to set population targets for health-enhancing physical activity when multi-domain instruments, such as IPAQ are used.1Pate RR, Pratt M, Blair SN, Haskell WL , Macera CA, Bouchard C et al.

Preliminary pedometer indices for public health. Sports Med. 2004;34(1):1-8.‘Moderate’This category is defined as doing some activity, more than the low active category. It is proposed that it is a level of activity equivalent to “half an hour of at least moderate-intensity PA on most days”, the former leisure time-based physical activity population health recommendation.‘Low’This category is simply defined as not meeting any of the criteria for either of the previous categories.5. Protocol for IPAQ Short Form5.1 ContinuousScoresMedian values and interquartile ranges can be computed for walking (W), moderate-intensity activities (M), vigorous-intensity activities (V) and a combined total physical activity score. All continuous scores are expressed in MET-minutes/week as defined below.5.2 MET Values and Formula for Computation of MET-minutes/weekThe selected MET values were derived from work undertaken during the IPAQ Reliability Study undertaken in 2000-20013. Using the Ainsworth et al. Compendium (Med Sci Sports Med 2000) an average MET score was derived for each type of activity. For example; all types of walking were included and an average MET value for walking was created. The same procedure was undertaken for moderate-intensity activities and vigorous-intensity activities. The following values continue to be used for the analysis of IPAQ data: Walking = 3.3 METs, Moderate PA = 4.0 METs and Vigorous PA = 8.0 METs. Using these values, four continuous scores are defined: Walking MET-minutes/week = 3.3 * walking minutes * walking daysModerate MET-minutes/week = 4.0 * moderate-intensity activity minutes * moderate daysVigorous MET-minutes/week = 8.0 * vigorous-intensity activity minutes * vigorous-intensity daysTotal physical activity MET-minutes/week = sum of Walking + Moderate + Vigorous MET-minutes/week scores.5.3 Categorical ScoreCategory 1 LowThis is the lowest level of physical activity. Those individuals who not meet criteria for Categories 2 or 3 are considered to have a ‘low’ physical activity level.3 Craig CL,Marshall A , Sjostrom M et al. International Physical Activity Questionnaire: 12 country reliability and validity Med Sci Sports Exerc 2003;AugustCategory 2 ModerateThe pattern of activity to be classified as ‘moderate’ is either of the following criteria:a) 3 or more days of vigorous-intensity activity of at least 20 minutes per dayORb) 5 or more days of moderate-intensity activity and/or walking of at least 30minutes per dayORc) 5 or more days of any combination of walking, moderate-intensity or vigorousintensity activities achieving a minimum Total physical activity of at least 600MET-minutes/week.Individuals meeting at least one of the above criteria would be defined as accumulating a minimum level of activity and therefore be classified as ‘moderate’. See Section 7.5 for information about combining days across categories.Category 3 HighA separate category labelled ‘high’can be computed to describe higher levels of participation.The two criteria for classification as ‘high’ are:a) vigorous-intensity activity on at least 3 days achieving a minimum Totalphysical activity of at least 1500 MET-minutes/weekORb) 7 or more days of any combination of walking, moderate-intensity orvigorous-intensity activities achieving a minimum Total physical activityof at least 3000 MET-minutes/week.See Section 7.5 for information about combining days across categories.in IPAQ Short Form5.4 SittingQuestionThe IPAQ sitting question is an additional indicator variable of time spent in sedentary activity and is not included as part of any summary score of physical activity. Data on sitting should be reported as median values and interquartile ranges. To-date there are few data on sedentary (sitting) behaviours and no well-accepted thresholds for data presented as categorical levels.6. Protocol for IPAQ Long FormThe long form of IPAQ asks in detail about walking, moderate-intensity and vigorous-intensity physical activity in each of the four domains. Note: asking more detailed questions regarding physical activity within domains is likely to produce higher prevalence estimates than the more generic IPAQ short form.6.1 ContinuousScoreData collected with the IPAQ long form can be reported as a continuous measure and reported as median MET-minutes. Median values and interquartile ranges can be computed for walking (W), moderate-intensity activities (M), and vigorous-intensity activities (V) within each domain using the formulas below. Total scores may also be calculated for walking (W), moderate-intensity activities (M), and vigorous-intensity activities (V); for each domain (work, transport, domestic and garden, and leisure) and for an overall grand total.6.2 MET Values and Formula for Computation of MET-minutesWork DomainWalking MET-minutes/week at work = 3.3 * walking minutes * walking days at workModerate MET-minutes/week at work= 4.0 * moderate-intensity activity minutes * moderate-intensity days at workVigorous MET-minutes/week at work= 8.0 * vigorous-intensity activity minutes * vigorous-intensity days at workTotal Work MET-minutes/week =sum of Walking + Moderate + Vigorous MET-minutes/week scores at work.Active Transportation DomainWalking MET-minutes/week for transport = 3.3 * walking minutes * walking days for transportation Cycle MET-minutes/week for transport= 6.0 * cycling minutes * cycle days for transportationTotal Transport MET-minutes/week = sum of Walking + Cycling MET-minutes/week scores for transportation.Domestic and Garden [Yard Work] DomainVigorous MET-minutes/week yard chores= 5.5 * vigorous-intensity activity minutes * vigorous-intensity days doing yard work (Note: the MET value of 5.5 indicates that vigorous garden/yard work should be considered a moderate-intensity activity for scoring and computing total moderate intensity activities.)Moderate MET-minutes/week yard chores= 4.0 * moderate-intensity activity minutes * moderate-intensity days doing yard workModerate MET-minutes/week inside chores= 3.0* moderate-intensity activity minutes * moderate-intensity days doing inside chores.Total Domestic and Garden MET-minutes/week =sum of Vigorous yard + Moderate yard + Moderate inside chores MET-minutes/week scores.Leisure-Time DomainWalking MET-minutes/week leisure = 3.3 * walking minutes * walking days in leisureModerate MET-minutes/week leisure = 4.0 * moderate-intensity activity minutes * moderate-intensity days in leisureVigorous MET-minutes/week leisure = 8.0 * vigorous-intensity activity minutes * vigorous-intensity days in leisureTotal Leisure-Time MET-minutes/week = sum of Walking + Moderate + Vigorous MET-minutes/week scores in leisure.Total Scores for all Walking, Moderate and Vigorous Physical ActivitiesTotal Walking MET-minutes/week = Walking MET-minutes/week (at Work + for Transport + in Leisure) Total Moderate MET-minutes/week total = Moderate MET-minutes/week (at Work + Yard chores + inside chores + in Leisure time) + Cycling Met-minutes/week for Transport + Vigorous Yard chores MET-minutes/weekTotal Vigorous MET-minutes/week = Vigorous MET-minutes/week (at Work + in Leisure)Note: Cycling MET value and Vigorous garden/yard work MET value fall within the coding range of moderate-intensity activities.Total Physical Activity ScoresAn overall total physical activity MET-minutes/week score can be computed as:Total physical activity MET-minutes/week = sum of Total (Walking + Moderate + Vigorous) MET-minutes/week scores.This is equivalent to computing:Total physical activity MET-minutes/week = sum of Total Work + Total Transport + Total Domestic and Garden + Total Leisure-Time MET-minutes/week scores.As there are no established thresholds for presenting MET-minutes, the IPAQ Research Committee proposes that these data are reported as comparisons of median values and interquartile ranges for different populations.Score6.3 CategoricalAs noted earlier, regular participation is a key concept included in current public health guidelines for physical activity.4 Therefore, both the total volume and the number of day/sessions are included in the IPAQ analysis algorithms. There are three levels of physical activity proposed to classify populations – ‘low’, ’moderate’, and ‘high’. The criteria for these levels are the same as for the IPAQ short [described earlier in Section 4.2]Category 1 LowThis is the lowest level of physical activity. Those individuals who not meet criteria for Categories 2 or 3 are considered ‘low’.Category 2 ModerateThe pattern of activity to be classified as ‘moderate’ is either of the following criteria:d) 3 or more days of vigorous-intensity activity of at least 20 minutes per dayORe) 5 or more days of moderate-intensity activity and/or walking of at least 30minutes per dayOR4Pate RR, Pratt M, Blair SN, Haskell WL , Macera CA, Bouchard C et al.

See Section 7.5 for information about combining days across categories.Category 3 HighA separate category labelled ‘high’can be computed to describe higher levels of participation.The two criteria for classification as ‘high’ are:a) vigorous-intensity activity on at least 3 days achieving a minimum Totalphysical activity of at least 1500 MET-minutes/weekORb) 7 or more days of any combination of walking, moderate-intensity orvigorous-intensity activities achieving a minimum Total physical activityof at least 3000 MET-minutes/week.See Section 7.5 for information about combining days across categories.6.4 IPAQ Sitting Question IPAQ Long FormThe IPAQ sitting question is an additional indicator variable and is not included as part of any summary score of physical activity. To-date there are few data on sedentary (sitting) behaviours and no well-accepted thresholds for data presented as categorical levels. For the sitting question ‘Minutes’ is used as the indicator to reflect time spent in sitting rather than MET-minutes which would suggest an estimate of energy expenditure.IPAQ long assesses an estimate of sitting on a typical weekday, weekend day and time spent sitting during travel (see transport domain questions).Summary sitting variables includeSitting Total Minutes/week = weekday sitting minutes* 5 weekdays + weekend day sitting minutes* 2 weekend daysAverage Sitting Total Minutes/day = (weekday sitting minutes* 5 weekdays + weekend day sitting minutes* 2 weekend days) / 7Note: The above calculation of ‘Sitting Total’ excludes time spent sitting during travel because the introduction in IPAQ long directs the responder to NOT include this component as it would have already been captured under the Transport section. If a summary sitting variable including time spent sitting for transport is required, it should be calculated by adding the time reported (travelling in a motor vehicle) under transport to the above formula. Care should be taken in reporting these alternate data to clearly distinguish the ‘total sitting’ variable from a ‘total sitting – including transport’ variable.7. Data Processing RulesIn addition to a standardized approach to computing categorical and continuous measures of physical activity, it is necessary to undertake standard methods for the cleaning and treatment of IPAQ datasets. The use of different approaches and rules would introduce variability and reduce the comparability of data.There are no established rules for data cleaning and processing on physical activity. Thus, to allow more accurate comparisons across studies IPAQ Research Committee has established and recommends the following guidelines:7.1 Data CleaningI. Any responses to duration (time) provided in the hours and minutes responseoption should be converted from hours and minutes into minutes.II. To ensure that responses in ‘minutes’ were not entered in the ‘hours’ column by mistake during self-completion or during data entry process, values of ‘15’, ‘30’, ‘45’, ‘60’ and ‘90’ in the ‘hours’ column should be converted to ‘15’, ‘30’, ‘45’, ‘60’ and ‘90’ minutes, respectively, in the minutes column.III. In some cases duration (time) will be reported as weekly (not daily) e.g., VWHRS, VWMINS. These data should be converted into an average daily time by dividing by 7.IV. If ‘don’t know’ or ‘refused ‘ or data are missing for time or days then that case is removed from analysis.Note: Both the number of days and daily time are required for the creation of categorical andcontinuous summary variables7.2 Maximum Values for Excluding OutliersThis rule is to exclude data which are unreasonably high; these data are to be considered outliers and thus are excluded from analysis. All cases in which the sum total of all Walking, Moderate and Vigorous time variables is greater than 960 minutes (16 hours) should be excluded from the analysis.This assumes that on average an individual of 8 hours per day is spent sleeping.The ‘days’ variables can take the range 0-7 days, or 8, 9 (don’t know or refused); values greater than 9 should not be allowed and those cases excluded from analysis.7.3 Minimum Values for Duration of ActivityOnly values of 10 or more minutes of activity should be included in the calculation of summary scores. The rationale being that the scientific evidence indicates that episodes or bouts of at least 10 minutes are required to achieve health benefits. Responses of less than 10 minutes [and their associated days] should be re-coded to ‘zero’.7.4 Truncation of Data RulesThis rule attempts to normalize the distribution of levels of activity which are usually skewed in national or large population data sets.In IPAQ short - it is recommended that all Walking, Moderate and Vigorous time variables exceeding ‘ 3 hours’ or ‘180 minutes’ are truncated (that is re-coded) to be equal to ‘180 minutes’ in a new variable. This rule permits a maximum of 21 hours of activity in a week to be reported for each category (3 hours * 7 days).In IPAQ long – the truncation process is more complicated, but to be consistent with the approach for IPAQ short requires that the variables total Walking, total Moderate-intensity and total Vigorous-intensity activity are calculated and then, for each of these summed behaviours, the total value should be truncated to 3 hours (180 minutes).When analysing the data as categorical variable or presenting median and interquartile ranges of the MET-minute scores, the application of the truncation rule will not affect the results. This rule does have the important effect of preventing misclassification in the ‘high’ category. For example, an individual who reports walking for 10 minutes on 6 days and 12 hours of moderate activity on one day could be coded as ‘high’ because this pattern meets the ‘7 day” and “3000 MET-min” criteria for ‘high’. However, this uncommon pattern of activity is unlikely to yield the health benefits that the ‘high’ category is intended to represent.Although using median is recommended due to the skewed distribution of scores, if IPAQ data are analysed and presented as a continuous variable using mean values, the application of the truncation rule will produce slightly lower mean values than would otherwise be obtained.MET-minute/week Scores7.5 CalculatingData processing rules 7.2, 7.3, and 7.4 deals first with excluding outlier data, then secondly, with recoding minimum values and then finally dealing with high values. These rules will ensure that highly active people remain classified as ‘high’, while decreasing the chances that less active individuals are misclassified and coded as‘high’.Using the resulting variables, convert time and days to MET-minute/week scores [see above Sections 5.2 and 6.2; METS x days x daily time].7.6 Calculating Total Days for Presenting Categorical Data on Moderate andHigh LevelsPresenting IPAQ data using categorical variables requires the total number of ‘days’ on which all physical activity was undertaken to be assessed. This is difficult because frequency in ‘days’ is asked separately for walking, moderate-intensity and vigorous-intensity activities, thus allowing the total number of ‘days’ to range from a minimumof 0 to a maximum of 21’days’ per week in IPAQ short and higher in IPAQ long. The IPAQ instrument does not record if different types of activity are undertaken on the same day.In calculating ‘moderately active’, the primary requirement is to identify those individuals who undertake activity on at least ‘5 days’/week [see Sections 4.2 and5.3]. Individuals who meet this criterion should be coded in a new variable called “at least five days” and this variable should be used to identify those meeting criterion b) at least 30 minutes of moderate-intensity activity and/or walking; and those meeting criterion c) any combination of walking, moderate-intensity or vigorous-intensity activities achieving a minimum of 600 MET-minutes/week.Below are two examples showing this coding in practice:i) an individual who reports ‘2 days of moderate-intensity’ and ‘3 days of walking’should be coded as a value indicating “at least five days”;ii) an individual reporting ‘2 days of vigorous-intensity’, ‘2 days of moderate-intensity’ and ‘2 days of walking should be coded as a value to indicate “atleast five days” [even though the actual total is 6].The original frequency of ‘days’ for each type of activity should remain in the data file for use in the other calculations.The same approach as described above is used to calculate total days for computing the ‘high’category. The primary requirement according to the stated criteria is to identify those individuals who undertake a combination of walking, moderate-intensity and or vigorous-intensity activity on at least 7 days/week [See section 4.2]. Individuals who meet this criterion should be coded as a value in a new variable to reflect “at least 7 days”.Below are two examples showing this coding in practice:i) an individual who reports ‘4 days of moderate-intensity’ and ‘3 days of walking’should be coded as the new variable “at least 7 days”.ii) an individual reporting ‘3 days of vigorous-intensity’, ‘3 days moderate-intensity’ and ‘3 days walking’ should be coded as “at least 7 days” [eventhough the total adds to 9] .algorithms8. SummaryThe algorithms in Appendix 1 and Appendix 2 to this document show how these rules work in an analysis plan, to develop the categories 1 [Low], 2 [Moderate], and 3 [High] levels of activity.IPAQ Research CommitteeNovember 2005。
