Evaluating the influence of low birth weight on food parenting practices in preschool children.

Food parenting practices, especially Autonomy Support practices and Structure practices, have not been comprehensively studied among parents of children born with low birth weight in Asia. The aim of this study was to investigate food parenting practices among parents of preschoolers who were born with low (<2500 g) and normal birth weight (≥2500 g) in Singapore. We recruited 197 parents of pre-school children (aged 3-5 years) who completed a socio-demographic questionnaire and the HomeSTEAD questionnaire, which examined food parenting practices. Among parents, 98 (49.8%) and 99 (50.2%) had children who were normal (NBW) and low birth weight (LBW) respectively. Parents of children with LBW had lower scores in one Autonomy Support practice (Encouragement) and three Structure practices (Meal setting, Planning and preparation of healthy meals, Rules and limits around unhealthy foods), after controlling for ethnicity and parental education. Parents of children with LBW also scored higher in one Autonomy Support practice (Guided choices: when food is given). There were no significant differences in Coercive Control practices between parents of both groups. Healthcare professionals could use this information to assess parental needs when facilitating parents' positive food parenting practices, especially among children with low birth weight.

Dietary intake and associations with myopia in Singapore children.

PURPOSE: To evaluate associations of dietary factors with myopia, spherical equivalent refractive error (SE) and axial length (AL) in children at age 9 from the Growing Up in Singapore Towards healthy Outcomes (GUSTO) birth cohort. METHODS: We included 467 multi-ethnic children (933 eyes) who participated in the GUSTO prospective birth cohort and were delivered in two major hospitals in Singapore (2009-2010). At the 9-year visit, we assessed the 6-year incidence of myopia (between ages 3 to 9), cycloplegic SE and AL in children without myopia (SE ≤ -0.5 D in either eye) at the 3-year visit. Using a validated 112-item food frequency questionnaire, parents reported each child's average daily intake of dietary factors (nutrients and food groups) in the past month. Paired eyes were analysed using Generalised Estimating Equations with multivariable logistic or linear regression. Bonferroni corrections were applied, correcting for multiple comparisons between the 13 nutrients (p < 0.004) or 8 food groups (p < 0.006) and each outcome. RESULTS: In children aged 9 years (51.0% boys; 56.3% Chinese), the 6-year incidence of myopia was 35.5%. Overall, the mean (SD) SE and AL were -0.3 (1.7) D and 23.4 (1.0) mm, respectively. In multivariable regression, macronutrients or micronutrients were not associated with incident myopia (p ≥ 0.004 for all), adjusting for total energy, gender, ethnicity, time outdoors, near-work and the number of myopic parents (additionally child's height for outcome AL). Similarly, all food groups (including refined grains, sugar-sweetened beverages, protein foods, fruits and vegetables) were not associated with incident myopia (p ≥ 0.006 for all). Additionally, none of the nutrients (p ≥ 0.004 for all) or food groups (p ≥ 0.006 for all) were associated with SE or AL. CONCLUSIONS: Our study findings of no significant association between specific nutrients or food groups and incident myopia or SE or AL suggest that diet may not be associated with myopia in children aged 9 years. Well-conducted prospective studies in other populations may clarify the association.

Factors influencing communication of traditional Chinese medicine use between patients and doctors: A multisite cross-sectional study.

OBJECTIVE: In Singapore, the use of traditional Chinese medicine (TCM) alongside Western medicine (WM) is common. There are risks of adverse herb-drug interactions when taken concurrently. Current literature suggests that TCM use is not regularly reported to WM doctors in Singapore, but the underlying reasons are not understood. METHODS: A cross-sectional study was conducted across Singapore by administering questionnaires to TCM-using patients and WM-practising general practitioners (GPs). The questionnaire examined the following themes: (1) demographics and TCM use pattern; (2) respondents' (patients and GPs) knowledge and beliefs about TCM and the factors influencing the discussion of TCM during the WM consultation; and (3) respondents' qualitative suggestions to increase disclosure rate. RESULTS: A total of 484 patients and 334 GPs were surveyed. Factors associated with patients' initiation of TCM discussion include length of consultation (odds ratio [OR]: 2.1; P < 0.001), comfort level in discussing TCM (OR: 1.6; P < 0.001) and belief in importance of discussion (OR: 1.4; P = 0.017). Doctor's initiation of discussion (74%) was the top patient-ranked factor influencing their discussion of TCM. For doctors, knowledge of TCM indications (OR: 2.2; P < 0.001), belief in importance of discussion (OR: 2.1; P < 0.001) and comfort level in discussing TCM (OR: 1.9; P = 0.001) were associated with their initiation of TCM use discussion. Possible WM-TCM interactions (58%) was the top doctor-ranked factor influencing their discussion of TCM. CONCLUSION: The discussion of TCM in a WM setting is multifactorial. Interventions include doctors' active screening for TCM use in patients and equipping doctors with TCM knowledge. Improving communication between patients and doctors is key to avoiding harmful herb-drug interactions.

The Impact of Macronutrients on Retinal Microvasculature among Singapore Pregnant Women during the Mid-Late Gestation.

BACKGROUND: Imbalanced macronutrient intakes can induce impairment of endothelial and vascular function, and further lead to metabolic and cardiovascular disease. However, little is known about the influence of such diets on endothelial and vascular dysfunction in pregnant women, even though high-fat diet is a known risk for pregnancy complications such as gestational diabetes and pre-eclampsia. OBJECTIVE: We aimed to assess the association between maternal macronutrient intakes (protein, fat and carbohydrates), dietary quality and retinal microvascular changes in a multi-ethnic Asian mother-offspring cohort. METHODS: Pregnant women (n = 614) with singleton pregnancies were recruited during their first trimester from June 2009 to Sep 2010. Maternal diet quality and macronutrient intakes, expressed as a percentage of total energy during pregnancy, were ascertained using 24 hr recalls and 3 d food diaries at 26-28 weeks gestation. Retinal examination was completed at the same clinic visit. Dietary quality was assessed and scored using the Health Eating Index in Asian Pregnant women (HEI-AP), while macronutrients intakes ware expressed as percentages of total energy and further log transformed for analysis. Associations were examined cross-sectionally by substitution models with the use of multiple linear regression. RESULTS: In adjusted model, each 20 points decrease in HEI-AP score was associated with a significant increase of 1.70 µm (p<0.05) in retinal venular calibre. Each 0.1 log increase in percentage of total fat intake was associated with a significant increment of 1.84 µm (p<0.05) in retinal venular caliber. Additionally, each 0.1 log increase in percentage of mono-unsaturated fat intake was associated with an increment of 1.84 µm (p<0.01) in retinal venular caliber. CONCLUSIONS: In this cross-sectional study, we found that women with higher fat and lower protein intakes, and lower diet quality tended to have wider retinal venular caliber, which is suggestive of suboptimal microvasculature.
