Abstract Objective: To measure dietary intakes of young children aged 12–24 months and to determine the impact of poor diets on stunting. Design: A quantitative food-frequency questionnaire was adapted, tested and standardised. Trained enumerators conducted in-depth interviews with the mothers/caregivers of the children. Forty stunted children in urban informal settlements and 30 stunted children in rural areas were selected and pair-matched with controls. The data were captured on the Food Finder Program of the Medical Research Council. Results: In both urban and rural areas, the diet of stunted and non-stunted groups did differ significantly and all diets were of poor nutritional quality. Conclusion: Diets in both areas resembled the recommended prudent diet, i.e. low in fat and high in carbohydrates. Poor quality diets were not the primary cause of stunting.

The amount and frequency of use of pesticides in vegetable farming have been shown to be high in the five farming areas in Al-Ain, UAE. The mean usage of all pesticides was high (6.81 g/m2) while the usage of organophosphorus pesticides (2.11 g/m2) was higher compared to the usage of all the other types of pesticides. A number of pesticides banned from use in the developed countries are still used in vegetable farming. The depletion of erythrocyte acetylcholinesterase (AChE) activity among farmworkers was positively correlated with the length (p<0.01), frequency(p<0.05) and the use of pesticides (p<0.0001) and inversely correlated with the use of personal protective equipment (p<0.05) and personal hygiene practice (p<0.05). The morbidity profile among farmworkers was positively correlated with the use of pesticides on the farms (p<0.0001) and the non-use of personal protection (p<0.05). The mean concentrations of all pesticide residues (1.19±0.09 mg/kg) and the organophosphorus pesticide residues (1.23±0.22 mg/kg) in the locally grown vegetables exceeded the respective MRLs by 4 and 6 times respectively. The mean concentrations for all pesticides and for organophosphorus pesticide residues in twelve of the thirteen vegetable commodities also exceeded the corresponding MRLs. The mean dietary intakes of all pesticide residues, as a percentage of ADI, were 14% and 17% respectively for the ethnic and farming populations, while corresponding values for organophosphorus pesticides were 37% and 45% respectively. However, the dietary intakes of pesticide residues exceeded the ADI for mixtures for the ethnic (137%) and the farming populations (163%). A review of congenital malformations among ethnic and immigrant non-farming populations has suggested an interplay of genetic, dietary and environmental factors. Methods are proposed to reduce the environmental exposure and the dietary intake of pesticide residues and these include the establishment of a pesticide register, the training of the farmworkers in the proper use of pesticides, the use of protective measures, alternate methods of farming, the proper processing of vegetables prior to consumption and a comprehensive risk assessment of reproductive and genetic toxicity of organophosphorus pesticides.

Swimming is a very popular sport among adolescents in the US. Little is known about the diet of competitive adolescent swimmers in the US but data from other countries indicate several inadequacies, including excessive intake of fat and lower than recommended intake of carbohydrate and several micronutrients that may affect athletic performance and bone accrual. We assessed usual diet, using a food frequency questionnaire and calcium checklist, among 191 adolescent males and females [91 swimmers (mean 13.7, s = 2.5 years) and 100 non-athletes (mean 14.4, s = 2.8 years)]. For both males and females, swimmers and non-athletes generally had similar average intakes of macro- and micro-nutrients, including higher than recommended amounts of total fat (36%) and saturated fat (12%), and inadequate amounts of calcium, vitamin D, and daily servings of fruits, vegetables, grains, and dairy products. This first study of nutritional intake among adolescent swimmers in the US suggests that dietary habits of adolescents who swim competitively may jeopardize optimal athletic performance and place them at risk for future chronic diseases, including osteoporosis.
