Many previous studies have reported higher levels of cardiovascular disease risk factors such as body weight and fatness, blood pressure and plasma total cholesterol among populations participating in modern society, compared to their more rural, traditional counterparts. It has been suggested that this may be related to differences in dietary and activity patterns; however, this suggestion is often based on separate surveys of different individuals or is made in the absence of objective measures of both dietary and activity patterns. This study examines the extent to which risk factors vary with residence, occupation and leisure activities among Western Samoan men, and examines the extent to which this is associated with variation in dietary and activity patterns. Three groups of men aged 18-40 years were surveyed, representing rural village residents (N = 43) and men employed in physically active (N = 73) and sedentary (N = 86) jobs in urban Apia.
Subsamples of these were also studied, representing contrasts in leisure activity. Body fatness and blood pressure were measured in all men, and plasma total- and HDL-cholesterol and estimated aerobic capacity were also studied in the subsamples. Diet and activity were estimated by 24-hour recalls. Body fatness is higher among urban employees, especially sedentary workers, and is not consistently related to either higher energy intake or lower energy expenditure. Systolic pressure is higher among villagers than employed men, and is not accounted for by differences in nutrient intake or energy expenditure. Plasma total cholesterol does not vary with residence, occupation or leisure activity patterns, despite substantial variation in energy expenditure. HDL-cholesterol, its ratio to total cholesterol, and the non-HDL-cholesterol fraction do vary among the groups, and indicate possible effects of both body fatness and activity.
Estimated aerobic capacity varies with residence, occupation and leisure activity patterns, consistent with differences in energy expenditure and possible self-selection for certain activity patterns. It is concluded that certain cardiovascular disease risk factors do vary with residence, occupation and leisure activities in Western Samoan men, however variation in dietary and activity patterns is not a sufficient explanation for risk factor variation.
