RESUMO
Background: Diet is a significant contributor to health and wellbeing of individuals. Aim: In this study we investigated patterns of dietary intakes, levels of nutrient inadequacies and associated sociodemographic, anthropometric and lifestyle factors among adults in Trinidad and Tobago. Method: The study was cross-sectional in nature. A convenience sample of 11783 persons from districts throughout Trinidad and Tobago completed a self-administered questionnaire comprising socio-demographic and lifestyle items. Anthropometry was self-reported with 15% of participants having measurements done according to recommended procedures. Dietary patterns were determined by principal component analysis (PCA) while nutrient intakes and adequacy were assessed using the NutriGenie 7.0 software and nutrient adequacy ratio (MAR) respectively. Foods were categorised as unprocessed/minimally processed and processed/ultra-processed. The University of The West Indies Ethics Committee approved the study. Results: Approximately 72.5% of participants met the Goldberg criteria for plausible reporting. The three predominant dietary patterns 'Typical', 'Fruits and Vegetables', and 'High Fat' explained 45% of the total variance in foods consumed. Processed/ultra-processed foods accounted for most of the energy (80%) and nutrients consumed. Nutrient inadequacies were observed for potassium, vitamins B12, D, E, K, fibre, magnesium; and iron among females. The mean adequacy ratio (MAR) for participants was 67%. MAR was positively associated with predominant dietary patterns independent of socioe demographic and lifestyle factors (p < 0.001). Conclusion: Irrespective of their nature, the predominant dietary pattern was associated with nutrient adequacy among participants. Reducing the risk of inadequate nutrient intakes may be addressed by increasing availability, access and consumption of appropriate sources of these micronutrients.

This study assessed dietary intakes, nutritional composition, and identified commonly eaten foods among Jamaicans in Florida. Dietary intake was assessed among 44 study participants to determine commonly eaten foods and nutrient composition. Weighed recipes were collected and analyzed to determine nutrient composition for traditional foods. Top foods that contributed to macronutrient and micronutrient intake were identified and adherence to dietary recommendations was evaluated. Mean daily energy intake was 2879 (SD 1179) kcal and 2242 (SD 1236) kcal for men and women respectively. Mean macronutrient intakes were above dietary recommendations for men and women. Top foods contributing to energy included rice and peas, sweetened juices, chicken, red peas soup, and hot chocolate drink. Results showed sodium intake was more than double the adequate intake estimate (1300-1500 mg). Findings highlight the need to include commonly eaten traditional foods in dietary questionnaires to accurately assess diet-related chronic disease risk. Findings have implications for risk factor intervention and prevention efforts among Jamaicans.

The number of days of data required to accurately estimate usual nutrient intake of children is not well established. This study aims to calculate the variability and the number of days required to estimate usual nutrient intake in children aged 13-32 months. This cross-sectional study, which is part of the BRISA Project in São Luís, Maranhão, Brazil, involved 231 children from April 2011 to January 2013. Socio-economic and demographic data were collected using a questionnaire, and 3 non-consecutive days of food consumption were collected using a 24-h dietary recall (24HDR) survey. Intrapersonal and interpersonal variability and variance ratio (VR) were obtained for each nutrient using the Multiple Source Method® program (version 1.0.1). The number of days (d) needed was calculated using the formula proposed by Black et al. for different correlation coefficients (r) (i.e. 0·7, 0·8 or 0·9). For the vast majority of nutrients, intrapersonal and interpersonal variability values of <1 were observed, with even smaller intrapersonal variabilities, resulting in low VR (<1). More days were needed to estimate intakes of soluble fibre (12), insoluble fibre (11), total fibre (10), vitamin C (9) and PUFA (7), while fewer days were needed for energy, carbohydrate, SFA, Ca, Fe, P and Zn (all had 2 d for r 0·9). However, most nutrients required one, two or three 24HDR for r 0·7, 0·8 or 0·9.
