Relationship of alcohol consumption to diet: a population-based study in Hawaii.

The relationship of alcohol use to diet was examined in 2272 male and 2337 female adults aged 45 y and older who provided a quantitative diet history during 1977-1979. Mean values for each dietary variable, adjusted for smoking, ethnicity, income, and education, were compared in each sex between abstainers and drinkers and by tertile of ethanol intake. Linear relationships with extent of drinking were also sought. Drinkers were found to be less obese than abstainers. Consumption of carbohydrate, vitamins, calcium, fruits, fruit juices, and raw vegetables was greater among abstainers whereas consumption of fat (particularly polyunsaturated fatty acids), cholesterol, zinc, meat, pickled vegetables, and dried fish was greater among drinkers. Because validations of dietary questionnaires have shown that alcohol consumption is more accurately recalled than food intake, the possibility of a residual confounding effect for these dietary variables should be considered in epidemiologic studies of alcohol and health.

Genetic variation in Hawaiian Drosophila. IV. Allozymic similarity between D. silvestris and D. heteroneura from the island of Hawaii.

The species are endemic to the newest island in the archipelago and are broadly sympatric. They are easily distinguished morphologically in both sexes. Using standard electrophoretic procedures, we have examined 25 loci encoding for structural proteins from 539 silvestris and 325 heteroneura collected at three widely-separated localities where the two species are sympatric. Pairwise comparisons within and between the species show the following coefficients of genetic identity (NEI'S I): within silvestris, 0.961 +/- 0.01; within heteroneura, 0.949 +/- 0.02; between silvestris and heteroneura, 0.939 +/- 0.01. Neither the differences within nor between the species are significant. There are no fixed allelic diffrences either within or between the species. At the three areas of sympatry, the species show gene frequency differences (P less than 0.05) at 9,11 and 13 loci respectively. This is not much different from the variation within either one of the species across the three localities. The two species have similar heterozygosity (H) levels (silvestris, 0.083; heteroneura, 0.089) and percent of polymorphic loci (both 0.37). It is suggested that despite their morphological divergence, these species are much more newly formed than classical sibling species. Significant allozymic differences may not have had time to accumulate.

Patterns of menopause: a study of certain medical and physiological variables among Caucasian and Japanese women living in Hawaii.

Comparisons were made between menopausal women and nonmenopausal controls among Caucasians and Japanese living in Honolulu, to investigate the extent of physical changes and clinical symptoms associated with menopause. The analysis was conducted using the multiphasic screening records of 170 menopausal cases and 162 nonmenopausal controls in Caucasians, and of 159 menopausal women and 187 nonmenopausal controls in Japanese. Discriminant function analysis was employed with relevant anthropometric, medical, and physiological variables. After adjusting for the linear and non-linear effects of age, only surgery and medication were retained as significant discriminant variables. Discriminant functions for Caucasian and Japanese groups were not found to be significantly heterogeneous. With regard to the discrimination of the menopausal and nonmenopausal groups, the data suggested that, while no clinical conditions other than those attributable to the effects of aging were significantly associated with the menopausal state, medication and surgical procedures for female disorders were significantly related to menopause.
