Our data suggest that higher plasma tHcy in the third trimester is a predictor of lower birth weight. In general, the dietary intake of B-vitamins and energy may be inadequate in our population, suggesting intervention is necessary.

A potent mutagenic compound, 2-amino-3-methylimidazo-[4,5-f]quinoline (IQ), isolated from broiled sardines, cooked beef and beef extract was tested for carcinogenicity in CDF1 mice of both sexes. Mice were given diet containing 0.03% IQ or control diet for up to 675 days. Tumors were observed mainly in the liver, forestomach and lung. In the mice given IQ, the incidences of these tumors were as follows: liver tumors - 41% in males and 75% in females; tumors of the forestomach - 41% in males and 31% in females; lung tumors - 69% in males and 42% in females. In the control mice, incidences of these tumors were as follows: liver tumors - 9% in males and 8% in females; tumors of the forestomach - 3% in males and 0% in females; lung tumors - 21% in males and 18% in females. The incidences of tumors in the liver, forestomach and lung were significantly higher in mice given IQ than in control mice.

This study aimed to describe the nutritional status and dietary patterns of Cambodian school-aged children compared with those in the South East Asian Nutrition Survey (SEANUTS; Indonesia, Malaysia, Thailand, and Vietnam in 2011) and to clarify the urban-rural differences using data from a nationally representative sample. The survey was conducted in 2014/2015 with a sample of 2020 children aged 6–17 years from 136 randomly selected schools. Standardized anthropometric measurements and a 1-day dietary survey by 24-h recall method were conducted. Extended analyses in the present study revealed that the difference between rural and urban areas was similar to that of the SEANUTS; the overall prevalence of stunting remained high (33.2%). Stunting was more prevalent in children living in rural areas than in those in urban areas (total: 36.4% vs. 20.4%). In contrast, the overall prevalence of overweight and obesity was not as high (3.1%), but was higher among urban children in all age groups compared with those living in rural areas (total: 6.4% vs. 2.3%). Overall, the dietary intake of children did not meet the local recommended dietary allowances, which was similar to the results of the SEANUTS and differed across urban and rural areas.

This study found that the age, sex-adjusted prevalence of diabetes and IFG in Ho Chi Minh City were 3.8 and 2.5%, respectively, a rapid increase in the recent decade. Our study also indicates that ageing, a high WHR level, overweight and a sedentary lifestyle may be important determinants of the increased prevalence of diabetes during this transition period in Vietnam.

This food frequency questionnaire measured the usual intake of major nutrients for Vietnamese adults living in Ho Chi Minh City and its urban area, where dietary patterns are similar to those of the Vietnamese population.
