Objective: Few studies have addressed the association between abdominal obesity, as measured by waist circumference (WC), and disability in the elderly. Moreover, those studies were cross-sectional and yielded inconsistent results. The objective of this study was to examine longitudinally the association between WC and self-reported disability among older adults. Research Methods and Procedures:A prospective cohort study was conducted from 2001 to 2003 in 3235 persons (1411 men and 1824 women) representative of the noninstitutionalized Spanish population ages 60 years and older. Baseline information was collected by home-based personal interviews and measurement of WC, weight, and height. Two years later, information on disability was obtained by telephone interview. The association of interest was summarized with odds ratios obtained by logistic regression. Results: Among persons reporting no disability at baseline, WC predicted disability 2 years later. After adjustment for age, education, tobacco use, alcohol consumption, and physical activity, men in the highest WC quintile had 2.17 (95% confidence interval, 1.15 to 4.09) times more risk of mobility disability and 4.77 (95% confidence interval, 2.50 to 9.13) times more risk of agility disability than those in the lowest quintile. Additional adjustment for BMI, chronic diseases, and cognitive function led to only a slight reduction in this association. Results were similar for women. No statistically significant association was observed between WC and restriction of daily activities, limitation in instrumental activities of daily living, and limitation in bathing or dressing, in either men or women. Discussion: WC predicts mobility and agility disability in old age. Avoidance of the highest values of WC might decrease the risk of disability in older adults.

The present study tests the hypothesis that higher consumption of bakery products, sweetened soft drinks and yogurt is associated with higher intake of energy, saturated fats, sugars and worse overall diet quality among Spanish children. This is a cross-sectional study covering 1112 children aged 6.0-7.0 years in four Spanish cities. Nutrient and food intake were obtained through a food-frequency questionnaire, and overall diet quality calculated using the healthyeating index (HEI) developed by Kennedy et al. (1995). Standardized methods were used to measure anthropometric variables. Associations of interest were summarized as the difference in nutrient and food consumption between the value of the fifth and the first quintile of consumption (dq) of bakery products, sweetened soft drinks or yogurt, adjusted for energy intake and BMI. Bakery products, sweetened soft drinks and yogurt supplied 15·5, 1·0 and 5·6 % energy intake respectively. Higher consumption of these three foods was associated with greater energy intake (P, 0·001), but not with higher BMI. Consumption of bakery products was associated with the proportion of energy derived from intake of total carbohydrates (dq 4·5 %, P, 0·001) and sugars (dq 2 %, P, 0·001), but did not show association with the HEI. Consumption of sweetened soft drinks was associated with a lower consumption of milk (dq 2 88 ml, P, 0·001) and Ca (dq 2 175 mg/d, P,0·001), and worse HEI (dq 22, P, 0·01). Consumption of yogurt, while associated with higher energy intake from saturated fats (dq 1·77 %, P, 0·001) and sugars (dq 2·02 %, P,0·001), showed no association with the HEI. Differences in the intake of nutrients and foods across quintiles of consumption of bakery products, sweetened soft drinks and yogurt were usually very small. We conclude that the impact of the consumption of bakery products, sweetened soft drinks and yogurt on the quality of the diet of Spanish children is only modest, although it may contribute to aggravating certain unhealthy characteristics of their diet, particularly excess energy, saturated fats and sugars. Therefore, consumption of bakery products and sweetened soft drinks should be moderated, and priority given to consumption of low-fat, low-sugar yogurt. Abbreviations: dq, value of the fifth minus the first quintile of consumption; FFQ, food-frequency questionnaire; HEI, healthy-eating index.

Work-related physical activity is not associated with body mass index and obesity. Obes Res. 2002;10:270 -276. Objective: To analyze the association of work-related physical activity (WRPA) and leisure-time physical activity (LTPA) with body mass index (BMI) and obesity in the Spanish adult population aged 20 to 60 years. Research Methods and Procedures:The data were taken from the 1993 Spanish National Health Survey. We analyzed a sample of 12,044 men and women representative of the Spanish population aged 20 to 60 years. BMI and frequency of obesity (BMI Ն 30 kg/m 2 ) were obtained from self-reported weight and height. Multiple linear regression and logistic regression models were constructed, adjusting for the main confounding factors. WRPA and LTPA were measured by two questions to classify subjects into four categories of physical activity. Results: Neither mean BMI nor percentage of obesity varied significantly (p Ͼ 0.05) by WRPA. Mean BMI was significantly higher (p Ͻ 0.01) in those who were inactive in their leisure time (25.90 kg/m 2 in men and 24.43 kg/m 2 in women) than in those who reported vigorous activity (24.42 kg/m 2 and 22.97 kg/m 2 in men and women, respectively). The odds ration (OR) for obesity decreased with increasing level of LTPA in both men (OR of 0.64 for vigorous activity) and women (OR ϭ 0.68), showing a statistically significant dose-response relation in both men (for linear trend, p ϭ 0.0021) and women (p ϭ 0.0245). Discussion: These results raise questions about the association between WRPA and obesity and suggest the need to reexamine models of the obesity epidemic that point to automation of the workplace as one of the major explanatory factors.

Objective: Classic cardiovascular risk factors, such as smoking, arterial hypertension and hypercholesterolaemia, cannot explain a substantial part of the geographic differences in cardiovascular mortality. Anthropometric and nutritional factors in early stages of life may contribute to adult cardiovascular disease. Therefore, this work examines certain anthropometric variables and diet among children aged 6 -7 y, living in four Spanish cities with widely differing ischaemic heart disease (IHD) mortality. Design and setting: Cross-sectional anthropometric and dietary survey in four cities in Spain. Subjects: A total of 1112 children (50.1% males, 49.9% females) attending public and private schools in Cadiz and Murcia, cities with a relatively high IHD mortality, and Madrid and Orense, cities with a relatively low IHD mortality. A standardized method was used to measure anthropometric variables, and a food-frequency questionnaire completed by subjects' mothers, to measure diet. Outcome measures: Body mass index (BMI), overweight (BMI > 17.6 kg=m 2 ), obesity (BMI > 20.1 kg=m 2 ) and intake of food and nutrients. Results: Children in the four cities showed a high prevalence of overweight (range across cities, 28.9 -34.5%) and obesity (8.5 -15.7%). They also had a moderately hypercaloric diet (range, 2078 -2218 kcal=day), marked by an excessive intake of lipids (45.0 -47.3% kcal), particularly saturated fats (16.6 -16.9% kcal), proteins (17.0 -17.3% kcal), sugars (20.0 -21.9% kcal) and cholesterol (161.6 -182.9 mg=1000 kcal=day), and a low intake of complex carbohydrates (17.5 -18.1% kcal) and fibre (19.6 -19.9 g=day). Compared with children in the two low-IHD-mortality cities, those in the two high-IHD-mortality cities had a greater BMI (mean difference, 0.61 kg=m 2 ; P ¼ 0.0001) and ponderal index (0.58 kg=m 3 ; P ¼ 0.0001) and a higher intake of energy (104 kcal=day; P ¼ 0.007), cholesterol (16.00 mg=1000 kcal=day; P ¼ 0.0001) and sodium (321 mg=day; P ¼ 0.0001). Inter-city differences in anthropometric variables remained after adjustment for birthweight. Conclusions: Intake of fats, especially saturated fats, and cholesterol should be reduced among Spanish children. It could contribute to a needed reduction of the high prevalence of overweight and obesity in children. If the differences in anthropometric variables and diet between children from the cities with high and low coronary mortality are maintained in future or continue into adulthood, this could contribute to consolidate or even increase the IHD mortality gradient across cities. The finding that differences in anthropometric variables are independent of birthweight suggests that the childhood, rather than intrauterine environment, is involved in the development of such differences.
