“…These men also were slightly older and weighed more than the other men. Mean BPs appear to have increased for the HAS men compared to the data collected by Weitz (1982) in 1971 (no comparative data are available for the LAS men). Mean SBP increased from 113.5 (1971; n ‫ס‬ 90) to 122.9 (1995; n ‫ס‬ 134) and mean DBP increased from 70.6 (1971; n ‫ס‬ 90) to 79.7 (1995; n ‫ס‬ 133).…”

“…During the late 1960s, Lang and Lang (1971) reported on the health of the population in the Khumbu area; they found no evidence of arteriosclerotic cardiovascular disease or hypertension and reported obesity as uncommon. Weitz (1982) collected BP data on Sherpa men living in the Khumbu in 1971. Because hypertension was uncommon with Sherpas at the time of early contact with the outside world, the Sherpas are an excellent group to study and to examine changes in nutritional status associated with lifestyle changes.…”

The relationship among potential risk factors (diet, adiposity, physical activity levels (PALs), and age) for elevated blood pressures (BP) was examined in 253 Sherpa men living in Kathmandu (low altitude sample: LAS) and in the Khumbu (high altitude sample: HAS) regions of Nepal. The study is based on data collected to assess nutritional status. Elevated BPs were highly prevalent among both samples of men (LAS: 21.7% and HAS: 24.8%). The highest percentage of elevated BP was found among the urban HAS (32.4%), while rural HAS had the lowest percentage (16.1%). Stepwise regression analyses showed that the BMI, age, and alcohol consumption were strong predictors of systolic blood pressure (SBP), and the BMI and age were strong predictors of diastolic blood pressure (DBP). No correlations were found among BP and intakes of sodium, calcium, potassium, or fat when all men (normotensive and elevated BP) were examined. Bivariate association between the BMI and BP showed that obese men were 8.6–9.1 times more likely to have elevated BP, and that alcohol consumers were 2.6 times more likely to have elevated BP. The results suggest that elevated BP is a problem for a large portion of male Sherpas and appears to be associated with an elevated BMI. A survey of the region only 30 years ago showed no cases of hypertension. Increasing adiposity, due primarily to decreasing PALS, places this population at risk of chronic illness in the future. Am.

In developing countries like India, where the incidence of protein-calorie malnutrition is high and mechanization is at a minimum, human labor provides much of the power for physical activity. This study presents anthropometric measurements, somatotypes, food intakes, energy expenditures, and work outputs of Oraon agricultural laborers of the Jalpaiguri district, West Bengal, in an attempt to identify the factors that predict high work productivity. Specifically, this study investigates 1) the relationship between morphological variation (anthropometric measurements and somatotype) and work productivity, 2) the nature and extent of the relationship between nutritional status and work productivity, and 3) the best predictor variables of work output. Classification of groups on the basis of median values of work output show that in the aggregate, the high productive groups are significantly younger than low-productive groups in both sexes. Before age-adjustment, the high productive groups show higher mean values of a few body dimensions, though these differ by sex, and both males and females exhibit a normal range of blood pressure and pulse rate values. Mean values of grip strength and back strength are higher in high-output men and women. Mean values of both food intake and energy expenditure are also higher among men in high-output groups, with only food intake higher in high-output women. However, after eliminating the effects of age, the differences between low-productive groups and high-productive groups in most of the variables are not significant. Productivity predictors in males consist of age, food intake and chest girth (inhalation). Females, on the other hand, show age and grip strength (left) as work output predictors.
