OBJECTIVES: Describing the distribution of physical activity in populations is of major importance for developing public health campaigns to prevent sedentarism. METHODS: A population-based survey conducted during 1997-1999 in Geneva, Switzerland, included 3410 randomly selected men (n = 1707) and women (n = 1703), aged 35 to 74 years. Percentiles P10, P50, and P90 summarised the distributions of the total energy expenditure and of the percents used in moderate intensity activities (3 to 3.9 times the basal metabolism rate (BMR), e.g., normal walking, household chores), and in high and very high intensity activities (> or = 4 BMR, e.g., brisk walking, sports). RESULTS: The total energy expenditure (median 2929 kcal/day in men, 2212 kcal/day in women) decreased with age. Prevalence of sedentarism, defined as less than 10% of total energy expended in > or = 4 BMR activities, was 57% in men and 70% in women. Men expended 12% (median) of their total energy in 3 to 3.9 BMR and 8% in > or = 4 BMR activities. Corresponding percentages in women were 11% and 5%. The highest prevalence of sedentarism was in older age, women, and lower socio-economic status persons. CONCLUSION: Most of Geneva population is sedentary. Promoting physical activity should target children, adults and elderly, and physical activities which would be both attractive and financially affordable by most people. 相似文献

BACKGROUND: Clarify the association between physical activity intensity and overweight/obesity. METHODS: Population-based 1997-2001 survey in Geneva, Switzerland (n=5,757, ages 35 to 74). Intensity of physical activity energy expenditure (EE) defined as percentage of total EE in moderate activities [3-3.9 x basal metabolism rate (BMR), e.g., normal walking, household chores] and high-intensity activities (> or =4 x BMR, e.g., brisk walking, sports). Overweight or obesity based on measured body mass index (BMI). RESULTS: Comparing participants in the lowest vs. the highest tertile of the percentage of high-intensity EE, the odds ratios (ORs) were, for obesity vs. normal weight, 2.8 (95% confidence interval: 2.0-3.8, P<0.0001) in men and 2.4 (1.7-3.4, P<0.0001) in women. For obese vs. overweight, the men/women ORs were 1.9 (1.4-2.6, P<0.0001)/1.5 (1.0-2.2, P<0.05). For overweight vs. normal weight, the men/women ORs were 1.4 (1.1-1.7, P<0.002)/1.7 (1.3-2.1, P<0.0001). Less or no relationship was found for the percentage of moderate-intensity EE. CONCLUSIONS: This cross-sectional study cannot determine whether exercise is an effective strategy for weight control or whether overweight or obese people exercise less. However, clear dose-response associations in both genders between obesity or overweight and energy expenditure in high (but not in moderate)-intensity activities are findings with potentially major public health implications meriting validation in an experimental intervention study. 相似文献

It is important to know how physical activity is incorporated in women's lives to assess ways they can feasibly attain and maintain lifelong healthy practices. This study aimed to determine whether patterns of activity differed among young women whose physical activity met nationally recommended levels from those who did not. The sample was 42 women (aged 18–30 years) who had completed an exercise intervention (22 from the exercise group, 20 from the control group). Participants recorded pedometer steps and physical activities in diaries including form, duration and perceived exertion during 12 randomly assigned weeks over 26 weeks. We divided the sample into quartiles of moderate to vigorous physical activity to examine the composition of physical activities per quartile. Walking and shopping comprised the majority of physical activity in the lowest quartile of moderate to vigorous physical activity. In the second and third quartiles, walking and household/childcare together comprised more than two-thirds of all activities. Only in the highest quartile was cardio activity (not including walking, shopping and household/childcare) the largest proportion of activity; this category stood alone as varying significantly across quartiles of moderate to vigorous physical activity (p < 0.005). Among these young adult women, self-reported “lifestyle” physical activity was not sufficient to meet recommended levels of moderate to vigorous physical activity. The one-quarter who met recommended levels of moderate to vigorous physical activity did so largely through purposeful physical activities directly associated with exercise. Further research is needed to refine means of more fully measuring physical activities that women frequently perform, with particular attention to household work, childcare and shopping and to differing combinations of activities and levels of exertion by which diverse women can meet the recommended levels. The findings of this small scale study reinforce the ongoing benefit of recommending structured, planned physical activity at moderate and vigorous levels of intensity to young, healthy women to ensure they obtain the health benefits. 相似文献

A study to predict energy requirements of national athletes, 84 males and 24 females in 9 and 4 different types of sports respectively, were conducted during centralised training. Parameters assessed were anthropometry, 3-day activity pattern and energy cost (kcal/min) of common activities to derive total daily energy expenditure (TDEE). Based on body mass index (BMI), 68 males or 81% and 19 females or 79% of the athletes were classified as normal. The mean body fat content for males and females were 13.8 ± 4.5% and 24.7 ± 5.3%, respectively. The mean daily activity pattern of males and females athletes were similar for light activities (16? hr or 68% of day), for moderate activities (3? hr or 15% of day in male, 4 hr or 17% in females) while moderate to heavy activities related to training were 4 hr (17%) and 3? hr (15%) in males and females, respectively. Energy cost of some common activities ranges from 1.00-3.00 kcal/min in males and 0.84-2.04 kcal/min in females, while values for jogging were 6.60 kcal/min and 5.62 kcal/min in males and females, respectively. The mean TDEE in male ranges from 2938 kcal (12.3 MJ) in boxers (57 kg) to 4861 kcal (20.3 MJ) in weightlifters (110 kg) while the mean TDEE in female ranges from 2099 kcal (8.8 MJ) in athletics (51 kg) to 3098 kcal (13.0 MJ) in basketball (61.4 kg). The calculated physical activity level (PAL) values using measured BMR for males and females athletes ranges from 1.99-2.58 and 1.77-2.34, respectively. In conclusion, the estimated energy requirement for the various sports event studied ranges from 44-55 kcal/kg/day in males and 38-50 kcal/kg/day in female athletes. 相似文献

This paper aims to report the physical activity pattern and energy expenditure of adults aged 18 - 59 years in the Malaysian Adults Nutrition Survey (MANS) carried out between October 2002 and December 2003. The survey included 7349 adults representative of Peninsular Malaysia (Northern, Southern, Central and East Coast), as well as Sabah and Sarawak. A total of 6926 adults, comprising 3343 men and 3583 women, completed the physical activity section of the survey. Physical activity data was obtained using a physical activity questionnaire and 24-hour physical activity recall. Basal metabolic rate (BMR) was calculated from Ismail et al. (1998) predictive equations; total energy expenditure (TEE) was then estimated through factorial calculations based on time allocated and energy cost of various activities. Physical activity level (PAL) was calculated as the ratio of TEE to BMR. It was found that almost three-quarters of Malaysian adults traveled by passive modes of transportation. Only a third reported having ever-exercised, and an even smaller proportion of the population (14%) had adequate exercise. The population also spent the majority of their time (74% of the day) in sedentary activities, such as sleeping or lying down; doing light intensity activities (15% of the day), and doing moderate to vigorous intensity activities (10% of the day). Mean BMR and TEE was significantly higher amongst men than women, while mean PAL values were similar for men [1.6 (1.6 - 1.7)] and women [1.6 (1.6 - 1.6)]. More men (16%) were categorised as having active PAL compared to women (10%), while more women (43%) were categorised as having sedentary PAL compared to their male counterparts (37%). The present study provides the first in-depth report of the physical activity pattern, and national estimates of energy expenditure and physical activity levels of Malaysian adults, and concluded that Malaysian adults are generally sedentary. It is thus important that physical activity be further promoted and integrated into the lives of the population, preferably through various health promotion efforts as well as through the commitment of the authorities in providing a suitable environment for an active lifestyle. 相似文献

It has been suggested that energy requirements are either proportional to the BMR (FAO/WHO/UNU, 1985) or to body weight (WHO, 1973). The present analysis sought to distinguish between these two possibilities by determining whether, in rural Gambian women, energy expenditure was more nearly proportional to the BMR or to body weight. For nine of eleven common daily activities energy expenditure expressed per kg body weight was significantly lower in heavier compared to lighter individuals, indicating that energy expenditure was not proportional to weight. Since, in a preliminary analysis, it was found that in Gambian women BMR was roughly proportional to weight raised to the power 0.5, energy expenditure was also compared per kg. For ten of the eleven activities there were no significant differences between different weight groups in the energy costs expressed per kg, and it follows from this that in Gambian women the energy cost of common daily activities was more nearly proportional to the BMR than it was to body weight. Possible reasons for and implications of these results are discussed. 相似文献

In a longitudinal study of pregnancy and lactation levels of physical activity and total energy expenditure (TEE) were measured in 32 rural Gambian women using an activity diary technique. TEE, which was higher than previously measured food intake in this community, ranged from a minimum of 9.6 MJ (2300 kcal)/d (1.7 X BMR) in the months January-March to a maximum of 11.3 MJ (2700 kcal)/d (2 X BMR) during the agricultural season (July-October). During pregnancy and early lactation women went less often to the fields and also reduced the amount of time spent walking and performing household tasks. Standardizing for season and for changes in BMR and the energy cost of activity, reductions in physical activity reduced TEE by 0.59 +/- 0.08 MJ (140 +/- 18 kcal)/d between the 28th week of gestation and 4 weeks post-partum (P less than 0.001). While reduced physical activity may have had an adverse effect on agricultural productivity, energy was spared for other processes including fetal growth and milk output immediately post-partum. Dietary supplementation was without effect on activity pattern. 相似文献

BACKGROUND: This study examined the components of energy balance in poor, free-living pregnant women living in an urban setting of a developing country. OBJECTIVES: We tested the following hypotheses: 1) energy intake increases in pregnancy and is greater than when nonpregnant and nonlactating (NPNL), 2) basal metabolic rate (BMR) increases in pregnancy and the increase is positively correlated with prepregnancy fatness, and 3) energy expenditure in activity decreases in pregnancy and is lower than in NPNL women. DESIGN: Pregnant women were studied at 14.8 +/- 3.4 (n = 40), 25.0 +/- 3.2 (n = 54), and 34.9 +/- 2.4 (n = 43) wk gestation, and NPNL women at baseline (n = 114) and at 3 (n = 103) and 6 (n = 93) mo. Energy intake was measured by using estimated diet records and energy expenditure by using the flex heart rate method. Time allocation in physical activity was assessed by observation. RESULTS: In pregnant women, body weight, BMR, and energy intake increased but total daily energy expenditure (TDEE) did not change significantly. There were no significant changes in time allocation to selected activities except for lying down. In comparison with NPNL control subjects, women in late pregnancy had higher energy intakes and BMRs. Values for TDEE were not significantly different, but pregnant women expended less energy in activity and allocated more time to 2 energy-saving activities and less time to 2 energy-demanding activities. CONCLUSION: A decrease in energy expenditure in activity and changes in time allocation are important ways in which pregnant women meet the energy demands of pregnancy. 相似文献

OBJECTIVE: Alcohol drinkers are generally considered to underreport their alcohol intake, but little is known about whether they correctly report their energy intake (EI). We assessed the validity of the reported energy intake of alcohol drinkers using the 24-hour urinary (U) excretion of potassium (K) and sodium (Na) as biomarkers. METHODS: A total of 2,124 men and 1,998 women 25 to 74 years of age with a 24-hour urine collection, a random sample of the Belgian Interuniversity Research on Nutrition and Health (BIRNH). were studied. Dietary intake (D), including alcohol consumption, was assessed by a one-day food record. Basal metabolic rate (BMR) was predicted from age, gender and weight. As a measure for the degree of reporting error, D-K/U-K, D-Na/U-Na, EI/U-K, Non-alcohol EI/U-Na (NAEI/U-Na), EI/U-Na, EI/U-creatinine and EI/BMR ratios were calculated and compared among non-, moderate and heavy drinkers in both genders. RESULTS: EI, NAEI and all seven ratios examined generally increased with the level of alcohol intake in both genders. After adjustment for age, body mass index, smoking and educational level, most ratios were significantly higher in moderate drinkers (p < 0.02 to p < 0.0001) and in heavy drinkers (all p < 0.0001) than in non-drinkers. These differences were most significant in male heavy drinkers. The exceptions were D-K/U-K, D-Na/U-Na and NAEI/U-Na in moderate and female heavy drinkers and EI/U-K in male moderate drinkers. The estimated amount of the overreporting of EI by heavy drinkers was 27.8% in men and 13.7% in women. CONCLUSIONS: This study provides evidence that EI and NAEI obtained from the BIRNH study was overreported among alcohol drinkers, especially among male heavy drinkers. It also indicates that EI from alcohol replaced EI from food. 相似文献

The energy cost of common daily activities in African women: increased expenditure in pregnancy? 总被引:1,自引:0,他引:1
M Lawrence J Singh F Lawrence R G Whitehead 《The American journal of clinical nutrition》1985,42(5):753-763
We have performed, by open-circuit indirect calorimetry, a total of 1546 measurements of energy expenditure on 142 nonpregnant, pregnant, or lactating Gambian village women. Of the 47 common daily activities measured, only 7 would be classified as moderate according to internationally accepted standards, the remainder being light (ie requiring less than 3.5 kcal/min). This was unexpected since many of the tasks, judged subjectively, appeared quite demanding. Furthermore there was no increase towards the end of pregnancy in the energy cost of a range of activities requiring 1-5 kcal/min and involving a variety of body movements, despite the substantial weight gains observed. Only for walking was there the expected increase in energy expenditure. Although in the past it has been assumed that the heavier pregnant women would require additional energy for activity, no special allowance for this is included in current dietary recommendations. The present results indicate that, for women from the developing world, no allowance is necessary. The finding that most activities were light is also of relevance to total energy requirements in this community. 相似文献

Measurements of basal (BMR) and resting (RMR) metabolic rates, maintenance (MEE) and total daily energy expenditures (TDEE) have been made in Colombian children 6-16 years of age classified as nutritionally normal (boys, n = 129; girls, n = 72) and marginally undernourished (boys, n = 171; girls, n = 74). TDEE/BMR ratios were calculated for comparison with those suggested by FAO/WHO/UNU (1985) and to provide data for children less than 10 years of age. TDEE was measured in free-living, individually calibrated subjects by the heart-rate method. TDEE/BMR increased significantly with age in boys from 1.60 to 1.84 in control subjects and 1.46 to 1.92 in undernourished boys. There was no significant increase with age in the girls. There were no statistically significant differences between nutritional groups but girls had significantly lower values than boys. There was a greater rate of increase in TDEE than BMR with age and girls spent more time in light activities and less in high level activities than boys. 相似文献

According to the report of the World Health Organization (1985), total energy expenditure (TEE) in human subjects can be calculated as BMR x physical activity level (PAL). However, other reports have pointed out limitations in the suggested procedure related to the % body fat of the subjects. The purpose of the present study was to evaluate the World Health Organization (1985) procedure in thirty-four healthy women with BMI 18-39 kg/m2. BMR and TEE were measured using indirect calorimetry (BMRmeas) and the doubly-labelled water method (TEEref) respectively. When assessed using the doubly-labelled water and skinfold-thickness methods, the women had 34 (SD 8) and 33 (SD 6) % body fat respectively. On the basis of guidelines provided by the World Health Organization (1985), 1.64 was selected to represent the average PAL of the women. Furthermore, PAL was also assessed by means of an accelerometer (PALacc), heart-rate recordings (PAL(HR)) and a questionnaire (PALq). These estimates were: PALacc 1.71 (SD 0.17), PAL(HR) 1.76 (SD 0.24), PALq 1.86 (SD 0.27). These values were lower than TEEref/BMRref, which was 1.98 (SD 0.21). BMR assessed using equations recommended by the World Health Organization (1985) (BMRpredicted) overestimated BMR by 594 (SD 431) kJ/24 h. However, when TEE was calculated as BMRpredicted x PALacc, BMRpredicted x PAL(HR) and BMRpredicted x PALq respectively, average results were in agreement with TEEref. Furthermore, TEE values based on BMRpredicted and PALacc, PAL(HR), PALq as well as on PAL = 1.64, minus TEEref, were significantly correlated with body fatness. When the same PAL value (1.64) was used for all subjects, this correlation was particularly strong. Thus, the World Health Organization (1985) procedure may give TEE results that are biased with respect to the body fatness of subjects. 相似文献

An energy balance study was conducted in eight lactating poor-income Indian women from delivery to 6 months. Energy intake and expenditure were assessed for 7 days every month (30-37 days). Every month, basal metabolic rate (BMR) and milk ingested by infants was measured. An energy balance was computed. As a group these women were in energy balance, indicated by small body weight changes with respect to time. However, only two of these women were in a positive energy balance. Women with higher body weight lost more weight. Estimated mean energy intake was higher than energy expenditure. BMR showed a slight but not significant fall during the second month of lactation and was not different from the BMR seen in 13 non-pregnant, non-lactating women matched for body weight from the staff of the Institute. The energy cost of lactation was 2.3 MJ (549 kcal), a figure that justifies the Recommended Dietary Allowance for energy recommended by FAO/WHO/UNU (1985) and ICMR (1989). 相似文献

OBJECTIVE: To examine total energy expenditure (TEE) in relation to occupation and reported leisure time activities in free-living Chinese adults, and to determine whether measured TEE values differ from current international dietary energy recommendations. SETTING AND SUBJECTS: Seventy three weight-maintaining adults aged 35-49 y, leading unrestricted lives in urban Beijing, with a wide variety of occupations. DESIGN AND METHODS: A cross-sectional study in which TEE was determined by doubly labeled water, body composition by deuterium oxide ((2)H(2)O) dilution, resting energy expenditure (pREE) by prediction equations, and occupational and leisure time activities by questionnaire. RESULTS: For men and women respectively, TEE averaged 12.10+/-0.32 and 9.53+/-0.23 MJ/day (P<0.001), and physical activity level (PAL=TEE/pREE) was 1.77+/-0.04 and 1.66+/-0.02 (P<0.05). Fat-free mass (FFM) was the single best predictor of TEE (adjusted r(2)=0.71, P<0.001). Occupational category (light, moderate and heavy) further predicted TEE, independent of FFM (adjusted multiple r(2)=0.82, P<0.001). Both TEE adjusted for weight and PAL increased with occupational category. Measured TEE was slightly but significantly higher than the 1985 FAO/WHO/UNU estimates for women with light occupations, but did not differ from estimates for men with light occupations, or for adults with moderate or heavy occupations. CONCLUSION: Level of occupational activity, but not duration or type of leisure activity, significantly predicted TEE in free-living urban Chinese adults. Current energy requirement recommendations slightly underestimated the energy needs of women with light occupations but were accurate for men and women with moderate and heavy occupations.

Energy cost of physical activity throughout pregnancy and the first year postpartum in Dutch women with sedentary lifestyles 总被引:2,自引:0,他引:2
J M van Raaij C M Schonk S H Vermaat-Miedema M E Peek J G Hautvast 《The American journal of clinical nutrition》1990,52(2):234-239
Basal metabolic rate (BMR), activity pattern, and energy costs of some daily activities were measured in 25 Dutch women throughout pregnancy and the first year postpartum. Physical activity index (PAI), which refers to daily energy expenditure expressed as a multiple of BMR, was calculated from activity-pattern data and activity costs. Mean PAIs (+/- SD) throughout pregnancy, during the first 6 mo postpartum, and at 1 y postpartum were 1.48 +/- 0.08, 1.49 +/- 0.07, and 1.53 +/- 0.10 X BMR, respectively. Because measured BMR at 1 y postpartum was 1440 +/- 168 kcal/d, costs for physical activity in pregnancy and the first 6 mo postpartum were, respectively, approximately 70 and approximately 50 kcal/d lower than at 1 y postpartum. For women with sedentary lifestyles the energy saved during pregnancy and lactation because of decreased physical activity and decreased costs of activities will be limited. 相似文献

亚热带地区哺乳妇女能量需要量的观察 总被引:2,自引:1,他引:1
以同地区的53名非哺乳育龄妇女作对照,对262名产后0~6月乳母的体重、皮脂、上臂围、基础代谢率(BMR)、能量消耗和摄入量分别进行横向和纵向观察。结果表明,产后乳母体重和皮脂厚度逐渐下降,至第4个月基本稳定,平均减重4.2kg,估计孕期的贮脂大部分已消耗。上臂围无明显变化(P>0.05)。乳母的BMR在产后第1周较高(P<0.01),1~6月无明显变化(P<0.05),但比对照组高4~20%(P<0.05)。乳母在同一标准活动耗能与对照组接近(P>0.05)。轻体力劳动乳母日均活动耗能8.360MJ,估计泌乳耗能为2.807MJ/d。乳母能量摄入量比对照组多2.259MJ/d。作者认为,亚热带产后0~6月乳母在正常哺乳情况下,头4个月每日能量需要量应在平日消耗量基础上增加1.883MJ(450kcal),后雨月增加2.720MJ(650kcal),或整个阶段平均增加2.092MJ/d(500kcal/d),但此值仍需按泌乳量和正常体重变化加以调节。 相似文献

We assessed the effects of changes in income and occupational activities on changes in body weight among 2952 non-pregnant women enrolled in the Cebu Longitudinal Health and Nutrition Surveys between 1983 and 2002. On average, body mass index (BMI) among women occupied in low activities was 0.29 kg/m(2) (standard error 0.11) larger compared to women occupied in heavy activities. BMI among women involved in medium activities was on average 0.12 kg/m(2) (standard error 0.05) larger compared to women occupied in heavy activities. A one-unit increase in log household income in the previous survey was associated with a small and positive change in BMI of 0.006 kg/m(2) (standard error 0.02) but the effect was not significant. The trend of increasing body mass was higher in the late 1980s than during the 1990s. These period effects were stronger for the women who were younger at baseline and for women with low or medium activity levels. Our analysis suggests a trend in the environment over the last 20 years that has increased the susceptibility of Filipino women to larger body mass. 相似文献
