Previous studies in Melanesians of Papua New Guinea have documented low serum cholesterol concentrations with no age-related rise and a virtual absence of coronary heart disease. However, because of recent reports of the emergence of coronary heart disease in this population, serum lipid concentrations in adults aged > or = 25 years in three coastal (n = 1,489 and three highland (n = 388) village communities at different stages of modernization were examined as part of a survey undertaken in 1991. Total cholesterol concentrations were clearly higher than were levels recorded in earlier studies. Moreover, age-related increases in total cholesterol, low density lipoprotein cholesterol (LDL cholesterol), high density lipoprotein cholesterol (HDL cholesterol), and triglycerides (in women) were apparent. Mean total cholesterol levels in an urban community with a high risk of diabetes were similar to those observed in Australians, while HDL cholesterol concentrations were lower. Total cholesterol and LDL cholesterol levels were higher in urban coastal and periurban highland subjects than in their rural counterparts. Prevalence of hypercholesterolemia (> or = 5.2 mmol/liter) varied from 16% in rural highlanders to 56% in urban coastal subjects. Sex, age, village, body mass index, fat distribution, glucose intolerance, physical activity, and an index of relative modernity all contributed to variations in cholesterol and triglyceride concentrations. These results show that Papua New Guineans are by no means protected from dyslipidemia and serve warning that, unless effective preventative strategies can be developed, this and similar rapidly developing populations can expect an increasing incidence of coronary heart disease.
The association between acculturation to a Western lifestyle and prevalence of diabetes was examined among 8,006 Japanese-American men in Hawaii with varying degrees of exposure to traditional Japanese social and cultural lifestyles in 1965-1968. A reduced prevalence of diabetes was observed among the men who had retained a more Japanese lifestyle. These men also reported higher levels of physical activity and consumed more carbohydrates and less fat and animal protein in their diet. An inverse association between diabetes and being born in Japan was observed independent of age, body mass index, physical activity, and percentages of calories from fat or carbohydrates (odds ratios = 0.67 and 0.66, 95% confidence intervals 0.49-0.93 and 0.48-0.91, respectively). The number of total years lived in Japan was inversely associated with prevalent diabetes after controlling for age, body mass index, and physical activity (odds ratio = 0.81, 95% confidence interval 0.68-0.96). Current Oriental diet (compared with Western diet) was inversely associated with prevalent diabetes after controlling for age, body mass index, and physical activity (odds ratio = 0.71, 95% confidence interval 0.50-0.98). These findings suggest that living a Japanese lifestyle is associated with a reduced prevalence of diabetes.
A group of Turkish drug-addicted out-patients (n = 34) is compared to a group of Swiss opiate-addicted outpatients (n = 145) with respect to age, sex, social status, the number of offspring, the age of initiation of drug addiction and the type of the drug used. The results revealed that the Turkish population showed a better prognostic profile when the age of initiation of drug addiction, the familial integration and multiple addiction are taken into account, 97.1% of the Turkish opiate-addicted patients belonged to the second-generation immigrant population. In this group, the median age at immigration to Switzerland was 14.2 +/- 2.1 (excluding the three patients born in Switzerland). The conflict between the group-oriented expectations of their families and the individual-oriented life style of the peer group is the main reason for social role confusion, identity disturbances, for feelings of guilt because of separation or for shame because of dependence from the family. Confusion in social roles as well as in the interpretation of identification and the development and integration of identity permitting the coexistence of both cultures are the main topics of psychotherapy of drug-addicted Turkish immigrants.
