Reports on serum uric acid (SUA) levels in Chinese populations are sparse, but there is evidence that hyperuricaemia and gout are not uncommon. This paper characterizes SUA levels, their correlates, and their relationship to blood pressure (BP) and prevalent high blood pressure (HBP) for urban and rural adult population samples in north China. ⋯ In addition to its strong association with body mass index, SUA is independently related to serum lipids, particularly triglycerides, and to serum glucose. While some of the univariate relation of SUA to BP is apparently due to the strong relation of body mass to both SUA and BP, a low order significant relation between SUA and BP remains with control for BMI.

Child feeding recommendations include breastfeeding beyond 12 months, however, some researchers have reported increased rates of malnutrition in breastfed toddlers. A negative association between growth and breast-feeding may reflect reverse causality; that is, the outcome (growth) is a determinant of the predictor (breastfeeding), and not vice versa. We examined this question with data from 134 Peruvian toddlers. ⋯ The negative association between breastfeeding and linear growth reflected reverse causality. Increased breastfeeding did not lead to poor growth; children's poor growth and health led to increased breastfeeding. Children's health must be considered when evaluating the association of breastfeeding with anthropometric outcomes.

Child mortality estimates in Beirut are presented for the late 1970s and the mid 1980s, and changes in socio-religious differentials of mortality across time are investigated. ⋯ The findings confirm the hypothesis of a reduction over time of religious-based child mortality differences in the capital city of Lebanon, in agreement with the pattern found for religious-based fertility differences. Comparisons with other countries in the region indicate that the war in Lebanon has slowed down the decline in child mortality, causing the country to loose its priviledged position among Arab countries.

Comparative Study
Trends of liver cirrhosis mortality in Europe, 1970-1989: age-period-cohort analysis and changing alcohol consumption.
Since the mid 1970s, a striking reduction in alcohol-related problems has been observed in many Western countries. Liver cirrhosis mortality is considered to be a major indicator of alcohol-related problems in the general population. The aim of the present study is to describe liver cirrhosis mortality trends in European countries between 1970 and 1989. ⋯ The age-period-cohort analysis allows targeting of health care and prevention programmes based on future trends. Aetiological and prognostic factors act differently in Europe. A better understanding of the trends would require more detailed information on alcoholism treatment rates, alcohol habits, viral hepatitic infections and other factors involved in the aetiopathogenesis of the disease.

Cape Town is undergoing rapid urbanization. South African vital statistics have routinely been stratified by racial categories but intra-urban and peri-urban geographical variations have been neglected. ⋯ Routine mortality data are more informative if stratified by robust and readily available indicators of socio-economic status such as residential area and racial category. Place of residence may distinguish risk strata as well as racial category, but the latter is helpful within socioeconomically heterogeneous residential areas.
