IPAQ体力活动问卷及其重测方法解析

体力活动测量技术的金标准—双标水法( Doubly Labeled Water )
• DLW的原理很简单：受试者摄入一定数量已知浓度的使用2H和18O两种同位素标记的双标水(2H218O)。双标水进入人体后均匀的分布于体内,参与体内的代谢过程。经过一段时间的代谢,2H 以2H2O 形式从体内消除,18O以H218O 和C18O2 两种形式消除。

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. Physical activity and public health. A recommendation from the Centers for Disease Control and Prevention and the American College of Sports Medicine. Journal of American Medical Association 1995; 273(5):402-7. and U.S. Department of Health and Human Services. Physical Activity and Health: A Report of the Surgeon General. Department of Health and Human Services, Centers for Disease Control and Prevention, National Center for Chronic Disease Prevention and Health Promotion, The Presidents' Council on Physical Fitness and Sports: Atlanta, GA:USA. 1996.f) 5 or more days of any combination of walking, moderate-intensity or vigorous-intensity activities achieving a minimum Total physical activity of at least 600 MET-minutes/week.Individuals meeting at least one of the above criteria would be defined as accumulating a moderate level of activity. 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。

ipaq问卷评分标准

ipaq问卷评分标准
IPAQ问卷是一种用于评估个人体力活动水平的工具，其评分标准主要基于
问卷中的问题来进行。

具体来说，IPAQ问卷会询问个人在过去的7天内，分别在强度较大的体育
活动、适度的体育活动、步行以及坐姿状态下所花费的时间。

根据这些信息，可以计算出个人的体力活动总量（MET-minutes/week），具体计算方法
如下：
1. 强度较大的体育活动：将个人在强度较大的体育活动中所花费的时间（分钟）乘以相应的强度系数（7-12METs），然后加总得到该部分的活动量。

2. 适度的体育活动：将个人在适度的体育活动中所花费的时间（分钟）乘以相应的强度系数（3-6METs），然后加总得到该部分的活动量。

3. 步行：将个人在步行中所花费的时间（分钟）乘以相应的强度系数（），然后加总得到该部分的活动量。

4. 坐姿状态：将个人在坐姿状态下所花费的时间（分钟）乘以相应的强度系数（），然后加总得到该部分的活动量。

最后，将以上四部分的活动量相加，即可得到个人的体力活动总量（MET-minutes/week）。

根据这个数值，可以将个人的体力活动水平分为以下几个等级：
低水平：<600MET-minutes/week
中等水平：MET-minutes/week
高等水平：>3000MET-minutes/week
需要注意的是，以上评分标准仅供参考，具体的评分标准可能因不同的研究或调查而有所差异。

体力活动水平的计算方法为：根据问卷中记录的每种体力活动的时间，分别乘以对应的计算系数，再求和得到总的体力活动量，再除以总的时间得到体力活动水平。

具体计算方法如下：
体力活动水平(MET) = (体力活动的时间x 计算系数) ÷总的时间
其中，体力活动的时间是指在回答问卷中提到的每种体力活动的时间，计算系数是指每种体力活动对应的计算系数，总的时间是指回答问卷中提到的每种体力活动的总时间。

例如，如果一个人在回答问卷中提到了走路1小时、运动0.5小时、自行车0.5小时、高强度体力活动0.5小时，那么他的体力活动水平可以用如下公式计算：
体力活动水平(MET) = (1 x 3 + 0.5 x 8 + 0.5 x 8 + 0.5 x 8) ÷(1 + 0.5 + 0.5 + 0.5)
= (3 + 4 + 4 + 4) ÷2.5
= 15= 6 MET
国际体力活动问卷(IPAQ)中计算系数的具体值如下表所示：
体力活动类型计算系数
走路3
运动8
自行车8
高强度体力活动8
通过使用这些计算系数，可以得出每种体力活动对应的体力活动水平(MET)值，再将这些值相加，得出总的体力活动水平。

通常情况下，体力活动水平在3 MET以上即被认为是较高的体力活动水平，可以帮助促进身体健康。

【摘要】随着科学技术的发展，新技术、新设备的应用，机动车辆使用的增加，人们的职业劳动强度降低，久坐少动生活方式增加，体力活动水平逐渐降低。

体力活动不足是心血管疾病、糖尿病、肥胖等的主要危险因素之一，因此，许多国家颁布了国家体力活动指南，评价居民体力活动水平，制定体力活动推荐量，以增加人们的体力活动，促进健康。

我国还没有自己的体力活动推荐量，本文就国际上的体力活动推荐量及评价标准进行综述，为研究中国居民体力活动水平、制定体力活动推荐量及评价标准提供资料。

体力状态评分标准

体力状态评分标准体力状态评分是对个人体力状况的综合评价，通过评分可以了解一个人的身体健康程度、体能水平以及可能存在的潜在问题。

合理的体力状态评分标准可以帮助人们更好地了解自己的身体状况，有针对性地进行体育锻炼和健身训练。

下面是一个针对成人的体力状态评分标准：一、体重指数（BMI）：BMI是评估身体质量及肥胖程度的一个指标。

计算公式为：体重（kg）/ 身高（m）的平方。

根据BMI指数，将体重分为以下几个等级：-偏瘦：BMI＜18.5-正常：18.5≤BMI＜24-超重：24≤BMI＜28-肥胖：BMI≥28二、静息心率：静息心率是指身体没有进行任何负荷的情况下的心率。

测量静息心率可以评估心血管系统的健康状况。

常规范围为每分钟60-100次，如果静息心率低于60次/分钟，可能存在心脏问题。

三、肺活量：肺活量是指一个人在深吸气的情况下，能够呼出的最大容积。

男性和女性的肺活量标准有所不同，一般根据年龄和性别来进行评估。

四、身体灵活性：身体灵活性是指肌肉和关节的活动范围。

可以通过一些灵活性测试来评估身体的灵活性，如坐位体前屈、肩关节灵活度等。

五、身体力量：身体力量是指肌肉的力量和耐力。

可以通过一些操作能力和力量测试来评估身体力量，如俯卧撑、引体向上、硬拉等。

六、身体耐力：身体耐力是指持续进行高强度身体活动的能力。

可以通过一些耐力测试来评估身体的耐力水平，如长跑、蛙跳、登山机等。

七、爆发力与速度：爆发力与速度是指肌肉瞬间发力的能力，以及完成一些动作所需要的时间。

可以通过一些爆发力和速度测试来评估身体的爆发力与速度，如立定跳远、短跑等。

根据以上评分标准，可以根据个人的数据进行评估，得出相应的体力状态评分。

有针对性地进行体育锻炼和健身训练可以帮助改善体力状态，提高身体健康水平。

但需要注意的是，每个人的身体情况和目标不同，应根据个体差异进行评估，找到适合自己的锻炼方式，合理安排锻炼计划。

【2】国际体力活动问卷中体力活动水平的计算方法

国际体力活动问卷（IPAQ）［1］是目前公认有效、且在国际上较为广泛使用的成年人（15～69岁）体力活动水平测量问卷之一，分为短卷和长卷2个版本，已用于中国人群研究，经检验具有较好的效度与信度［2-5］。

问卷开发工作组公开发布了长卷和短卷的数据清理、体力活动水平计算和分组原则［6］，但由于语言障碍以及方案中对计算方法的表述不够清楚，不同使用者在数据分析时因理解不同可能会采用不同的处理方法，因此影响结果的可比性。

本文介绍IPAQ长卷和短卷的体力活动水平计算方法，方便我国学者使用。

基本原理IPAQ长卷共27道问题，其中25道询问个体的体力活动情况，2道询问个体的静坐情况。

体力活动情况主要由活动类型（工作、交通出行、家务园艺、休闲）和活动强度（步行及中等、高强度）构成。

依次询问个体过去7d内与工作、交通出行、家务园艺和休闲相关的体力活动。

在每类活动中，进一步询问3种不同强度体力活动的1周频率（d/w）和每天累计时间（min/d）。

表1展示了IPAQ长卷中各项体力活动的属性及其代谢当量（MET）赋值。

IPAQ短卷共7道问题，其中6道询问个体的体力活动情况。

问题结构与长卷相同，仅保留活动强度的部分。

短卷仅简单地分步行、中等强度和高强度询问不同强度活动的1周频率和每天累计时间，但在各强度中调查对象仍然需要综合考虑上述4类体力活动。

IPAQ 短卷中步行的MET赋值为3.3，中等强度活动的赋值为4.0，高强度活动的赋值为8.0。

体力活动问卷短卷及评分标准

体力活动问卷短卷及评分标准1. 体力活动问卷短卷概述嗨，大家好！今天咱们来聊聊体力活动问卷短卷，听起来是不是有点复杂？别担心，我会把它讲得简单易懂，让大家一听就明白。

首先，体力活动问卷短卷是为了帮助我们了解自己的运动习惯和体力活动水平。

说白了，就是通过这个问卷，咱们能知道自己每天到底动了多少，动得是否够、对身体有没有帮助。

你知道，有时候我们自己都不知道自己动了多少，可能觉得走了几步就是运动，其实这不一定对哦。

2. 体力活动的基本定义2.1. 什么是体力活动？体力活动，其实就是咱们日常生活中所有让身体动起来的行为。

别小看这点运动，像是上下楼梯、走路、甚至是打扫卫生都算在内。

听上去是不是有点像在给自己找借口？但这些真的能帮助我们保持健康，避免久坐带来的各种麻烦。

要知道，体力活动可不仅仅是去健身房挥汗如雨，平时多走几步、偶尔跳跳绳，也能为健康加分。

2.2. 为啥要填问卷？填问卷的目的就是要搞清楚你平时的运动量到底是多少。

通过填写问卷，我们能更好地了解自己每天的体力活动情况。

就像咱们买车时，得看一看车的性能参数，才能决定这车是不是适合我们一样。

体力活动问卷就像是我们健康的“性能参数”，帮我们找到自己运动的盲点，也让我们对未来的健康目标有个清晰的方向。

3. 问卷的填写指南3.1. 问卷内容概述这份问卷一般会问你一些关于运动频率、运动时间、运动强度的问题。

可能会问到你每天走多少步、每周运动几次、每次运动多久等。

这些问题看似简单，但其实能给我们提供很多有用的信息。

别觉得这些问题小儿科，实际上它们能帮助咱们深入了解自己运动的实际情况，找到可能的改善空间。

3.2. 如何正确填写在填写问卷时，咱们需要老实回答，不要为了好听的答案而胡编乱造。

想想你平时的生活习惯，认真回忆一下你运动的频率和强度。

有时候，我们可能觉得自己走了不少路，但实际上还是偏少，这就需要在填写问卷时诚实些。

如果你能如实填写，最终你得到的评估结果才会更准确，才能更好地帮助你制定未来的运动计划。

charls体力活动水平的计算方法

charls体力活动水平的计算方法【实用版3篇】目录（篇1）1.介绍 CHARLS 体力活动水平的计算方法2.说明计算方法的优点和局限性3.举例说明如何使用该计算方法4.总结 CHARLS 体力活动水平的计算方法正文（篇1）一、介绍 CHARLS 体力活动水平的计算方法CHARLS（中国老年健康与养老追踪调查）是我国一项重要的老龄化研究项目，其目的是为了解我国老年人的健康状况、养老需求和养老服务利用情况。

在 CHARLS 项目中，体力活动水平是评估老年人健康状况的重要指标之一。

本文将介绍 CHARLS 中计算老年人体力活动水平的方法。

二、计算方法的优点和局限性CHARLS 采用的体力活动水平计算方法具有一定的科学性和实用性。

其优点主要表现在以下几个方面：1.量化：该计算方法可以将复杂的体力活动行为简化为可度量的指标，便于分析和比较。

2.客观性：该方法通过对参与者的实际行为进行观察和记录，减少了主观判断的影响，提高了研究结果的客观性。

然而，任何研究方法都有其局限性，CHARLS 采用的计算方法也不例外。

其局限性主要表现在以下几个方面：1.测量误差：由于人力和时间的限制，计算过程中可能出现一定的测量误差。

2.不能完全反映个体差异：该计算方法以群体为研究对象，可能无法充分体现个体之间的差异。

三、举例说明如何使用该计算方法以一位 65 岁的老年人为例，假设他/她每天进行以下活动：1.早晨散步 30 分钟2.中午做饭 1 小时3.下午购物 1 小时4.晚上打扫卫生 1 小时根据 CHARLS 体力活动水平的计算方法，该老年人每天的体力活动水平可计算如下：(30 分钟/60 分钟) + (1 小时/60 分钟) + (1 小时/60 分钟) + (1 小时/60 分钟) = 0.5 + 0.16667 + 0.16667 + 0.16667 = 0.9 因此，该老年人的体力活动水平为 0.9。

四、总结总之，CHARLS 体力活动水平的计算方法是一项具有一定科学性和实用性的研究方法。

ROC曲线法建立大学生健康体力活动水平参考标准

ROC曲线法建立大学生健康体力活动水平参考标准作者：杨洪杰刘善云来源：《体育学刊》2022年第04期摘要：分析大学生体力活动水平、静坐时间与功能动作、身体素质表现的相关性，建立大学生健康体力活动水平和适宜静坐时间参考标准。

体力活动met标准

体力活动met标准你们知道吗？我们每天做的各种活动，像跑步呀、跳绳呀、甚至是走路，都可以用这个标准来衡量呢。

比如说，咱们在学校课间的时候，慢悠悠地走路去操场，这就是一种体力活动。

按照这个met标准呢，这种轻松的走路消耗的能量就比较少。

就好像小蚂蚁慢慢爬一样，虽然在动，但是没费太多力气。

再说说跳绳吧。

跳绳的时候我们可就像小兔子一样蹦蹦跳跳的。

这个时候呀，我们消耗的能量就比走路多很多啦。

按照那个met标准来说，跳绳的数值就比较高。

我有个好朋友，他特别喜欢跳绳。

有一次我们比赛跳绳，他一口气跳了好多好多下。

跳完之后呀，他就喘着粗气，脸蛋红扑扑的，就像个熟透的小苹果。

这就说明跳绳这个活动让他的身体费了不少劲儿，消耗了很多能量呢。

还有跑步的时候，就像是一阵小旋风。

在体育课上，老师让我们跑圈。

我们跑起来的时候，感觉风在耳边呼呼地吹。

这个时候，按照met标准，跑步消耗的能量可就更多啦。

我记得有一次学校举办运动会，有个同学参加了长跑比赛。

他跑的时候，汗水不停地从额头流下来，就像小溪一样。

他的腿不停地交替着往前迈，每一步都充满了力量。

这就表明跑步这个体力活动是很消耗能量的，在met标准里也是比较高的数值。

那这个met标准对我们有什么用呢？其实呀，它可以让我们知道自己做的活动有多“厉害”。

如果我们想要让自己的身体更健康，更强壮，就可以根据这个标准来选择合适的活动。

比如说，要是今天感觉有点懒，就可以先从轻松的走路开始，慢慢地增加活动量。

要是精力特别充沛，像充满电的小机器人一样，那就可以去跳绳或者跑步啦。

而且呢，不同的季节我们也可以根据这个标准来调整活动。

夏天的时候，天气特别热，像个大火炉。

这个时候我们可能就不太想做特别剧烈的活动，那就可以选择像散步这样的低met值的活动。

冬天呢，天气冷，我们就像小企鹅一样裹得厚厚的，但是也可以勇敢地去跑步，让自己热起来，这时候跑步的高met值就能让我们的身体快速暖和起来。

中小学体育课程中学生体力水平的评估方法研究

中小学体育课程中学生体力水平的评估方法研究随着现代社会的发展，中小学生的体力水平逐渐下降，这对于他们的身体健康和学习成绩都有一定的影响。

因此，如何科学地评估学生的体力水平，成为了中小学体育课程中的一项重要任务。

本文将探讨中小学体育课程中学生体力水平的评估方法。

首先，我们可以使用体能测试来评估学生的体力水平。

体能测试是通过一系列的体力项目来检测学生的身体素质，如耐力、力量、速度等。

常见的体能测试项目有跑步、跳远、引体向上等。

通过这些测试项目，我们可以了解学生的整体体力水平，并据此制定相应的训练计划。

然而，体能测试也存在一些问题，比如测试项目的选择可能不够全面，不能全面反映学生的体力水平。

其次，我们可以使用体质指数（BMI）来评估学生的体力水平。

BMI是一种常用的身体质量指数，通过计算学生的身高和体重之比来判断其体型是否健康。

然而，BMI只能反映学生的体重状况，不能全面反映其体力水平。

因此，在使用BMI评估学生的体力水平时，还需要结合其他指标进行综合评估。

除了体能测试和BMI，我们还可以使用心肺功能测试来评估学生的体力水平。

心肺功能是人体运动时心脏和肺部的工作能力，是体力水平的重要指标之一。

常见的心肺功能测试项目有静态心率测试、有氧运动测试等。

通过这些测试项目，我们可以了解学生的心肺功能水平，从而评估其体力水平。

然而，心肺功能测试也存在一些局限性，比如测试环境的限制和测试结果的主观性。

此外，我们还可以使用体适能测试来评估学生的体力水平。

体适能是指人体在运动中的适应能力，包括耐力、力量、速度、柔韧性等方面。

常见的体适能测试项目有仰卧起坐、立定跳远、引体向上等。

通过这些测试项目，我们可以全面了解学生的体适能水平，从而评估其体力水平。

然而，体适能测试也存在一些问题，比如测试项目的选择可能不够全面，不能全面反映学生的体力水平。

综上所述，中小学体育课程中学生体力水平的评估方法有多种选择。

体能测试、BMI、心肺功能测试和体适能测试都可以作为评估学生体力水平的工具。
