Home gardening is associated with Filipino preschool children's dietary diversity.

Dietary diversification through home gardening is a sustainable strategy that can address multiple micronutrient deficiencies. This cross-sectional study aimed to determine the association between home gardening and the dietary diversity of preschool-aged children. Households with children aged 2 to 5 years (n=200) were surveyed from Baras and Angono in the province of Rizal, Philippines in January 2008. Food security was determined based on the US Department of Agriculture Food Security Questionnaire. Dietary diversity score was based on the number of unique food groups consumed during the past 24 hours. The Student t test was performed to compare means between groups (households with gardens vs households without gardens) whereas proportions between groups were compared using Pearson's χ(2) analyses. Multiple linear regression was performed to model the adjusted regression coefficients for the quantitative outcome variables by exposure variable. Around 52.5% of children were from households with a fruit and/or vegetable garden. Children from households with gardens had higher dietary diversity scores whether using the all-inclusive dietary diversity score (6.12 vs 5.62; P=0.040) or applying a 10-g minimum intake for each food group (5.89 vs 5.37; P=0.044) compared with children who lived in homes without a garden. Children from households with gardens were significantly more likely to eat vegetables more frequently (χ(2)=9.06; P=0.029). The presence or absence of a garden was not significantly associated with food security. Having a home garden was positively associated with the child's diet diversity and with frequency of vegetable consumption. Households without gardens may benefit from interventions promoting gardens as a means to improve diet quality.

Physical activity, energy requirements, and adequacy of dietary intakes of older persons in a rural Filipino community.

BACKGROUND: Aging is a process associated with physiological changes such as in body composition, energy expenditure and physical activity. Data on energy and nutrient intake adequacy among elderly is important for disease prevention, health maintenance and program development. METHODS: This descriptive cross-sectional study was designed to determine the energy requirements and adequacy of energy and nutrient intakes of older persons living in private households in a rural Filipino community. Study participants were generally-healthy, ambulatory, and community living elderly aged 60-100 y (n = 98), 88 of whom provided dietary information in three nonconsecutive 24-hour food-recall interviews. RESULTS: There was a decrease in both physical activity and food intake with increasing years. Based on total energy expenditure and controlling for age, gender and socio-economic status, the average energy requirement for near-old (>or= 60 to < 65 y) males was 2074 kcal/d, with lower requirements, 1919 and 1699 kcal/d for the young-old (>or= 65 to < 75 y) and the old-old (>or= 75 y), respectively. Among females, the average energy requirements for the 3 age categories were 1712, 1662, and 1398 kcal/d, respectively. Actual energy intakes, however, were only approximately 65% adequate for all subjects as compared to energy expenditure. Protein, fat, and micronutrients (vitamins A and C, thiamin, riboflavin, iron and calcium) intakes were only approximately 24-51% of the recommended daily intake. Among this population, there was a weight decrease of 100 g (p = 0.012) and a BMI decrease of 0.04 kg/m2 (p = 0.003) for every 1% decrease in total caloric intake as percentage of the total energy expenditure requirements. CONCLUSION: These community living elderly suffer from lack of both macronutrient intake as compared with energy requirements, and micronutrient intake as compared with the standard dietary recommendations. Their energy intakes are ~65% of the amounts required based on their total energy expenditure. Though their intakes decrease with increasing age, so do their energy expenditure, making their relative insufficiency of food intake stable with age.

Efficacy of pandesal baked from wheat flour fortified with iron and vitamin a in improving the iron and anthropometric status of anemic schoolchildren in the Philippines.

OBJECTIVE: To determine the efficacy of pandesal baked from wheat flour fortified with iron, with or without vitamin A (VA), in improving anemic schoolchildren's iron and anthropometric status. METHODS: Anemic 6- to 12-year-old Filipino children (n = 250) received two 60 g pandesal daily for 8 months. They were randomized into 1 of 4 groups: (1) iron-fortified (with hydrogen-reduced iron at 80 mg/kg, electrolytic iron at 80 mg/kg, or ferrous fumarate at 40 mg/kg), (2) iron and VA-fortified, (3) VA-fortified (at 490 RE/100 g), and (4) nonfortified flour. Hemoglobin (Hb) and zinc protoporphyrin (ZnPP) concentrations and weight and height were determined before and after intervention. Analyses of variance and chi-square and multiple regression analyses were performed. RESULTS: Mean Hb increased by 1.3 g/dL (p < 0.001) and mean ZnPP decreased by 24.4 micromol/mol (p < 0.001) after 8 months. Anemia decreased to 26% and iron deficiency decreased from 58% to 12%. After controls were applied for baseline concentration, age, and gender, Hb concentration at post intervention was significantly higher in the Iron + VA group than in the nonfortified group (coefficient = 0.37; p = 0.034). The odds of being iron deficient at post intervention were significantly lower in the Iron group than in the nonfortified group after controls were applied for age, gender, and baseline prevalence (coefficient = 0.12; p = 0.006). None of the 3 fortified groups had significantly different weight-for-age z-score, body mass index-for-age z-score, or height-for-age z-score compared with the nonfortified group after controls were applied for baseline z-scores, age, and gender. CONCLUSIONS: Our study shows that in a non-malaria-endemic area, iron fortification of flour significantly reduced the prevalence of iron deficiency among anemic schoolchildren, and double fortification with iron and VA significantly improved Hb status.
