“…This is unlikely given that folate biomarkers and repeated food frequency questionnaire assessments of folate intake exhibit comparable correlations (~0.5-0.7) over periods of weeks to years.

Prenatal multivitamin/folic acid supplement use may reduce the risk of autism spectrum disorders. We investigated whether 2nd trimester prenatal vitamin use and maternal whole blood folate (WBF) concentrations were associated with Social Responsiveness Scale (SRS) scores at 4-5 years of age in a prospective cohort of 209 mother-child pairs. After confounder adjustment, children born to women taking prenatal vitamins weekly/daily (n=179) had lower odds of clinically elevated SRS scores (odds ratio:0.26; 95% confidence interval [CI]:0.08, 0.89) than those who rarely/never took them (n=30). WBF concentrations were not associated with SRS scores. The lack of association between WBF and autistic-behaviors may be due to the timing of biomarker measures relative to critical periods of brain development, confounding, or other modifying factors.

“…The DHQ was designed to assess the dietary intake of Japanese adults over the previous month8, 9, 10, 11 and has been previously validated for some fatty acids and vitamins in pregnant Japanese women 25, 26, 27, 28. Estimates of dietary intake for a total of 150 food and beverage items were calculated using an ad hoc computer algorithm, which included weighting factors for the DHQ.…”

BackgroundAccurate and easy dietary assessment methods that can be used during pregnancy are required in both epidemiological studies and clinical settings. To verify the utility of dietary assessment questionnaires in pregnancy, we examined the validity and reliability of a self-administered diet history questionnaire (DHQ) and a brief-type self-administered diet history questionnaire (BDHQ) to measure energy, protein, sodium, and potassium intake among pregnant Japanese women.MethodsThe research was conducted at a university hospital in Tokyo, Japan, between 2010 and 2011. The urinary urea nitrogen, sodium, and potassium levels were used as reference values in the validation study. For the reliability assessment, participants completed the questionnaires twice within a 4-week interval.ResultsFor the DHQ (n = 115), the correlation coefficients between survey-assessed energy-adjusted intake and urinary protein, sodium, and potassium levels were 0.359, 0.341, and 0.368, respectively; for the BDHQ (n = 112), corresponding values were 0.302, 0.314, and 0.401, respectively. The DHQ-measured unadjusted protein and potassium intake levels were significantly correlated with the corresponding urinary levels (rs = 0.307 and rs = 0.342, respectively). The intra-class correlation coefficients for energy, protein, sodium, and potassium between the time 1 and time 2 DHQ (n = 58) and between the time 1 and time 2 BDHQ (n = 54) ranged from 0.505 to 0.796.ConclusionsBoth the DHQ and the BDHQ were valid and reliable questionnaires for assessing the energy-adjusted intake of protein, sodium, and potassium during pregnancy. In addition, given the observed validity of unadjusted protein and potassium intake measures, the DHQ can be a useful tool to estimate energy intake of pregnant Japanese women.

Objective: A growing body of evidence from Western countries shows that infant feeding practices are associated with later childhood dietary habits, but little is known about these relationships in non-Western countries with different food cultures. We examined the association of breast-feeding duration and age at introduction of solid foods with later intake of fruit and vegetables among Japanese toddlers. Design: Information on breast-feeding duration, age at introduction of solid foods and child's intake frequency of fruit and vegetables were collected with a selfadministered questionnaire at 16-24 months postpartum. Logistic regression analysis was used to calculate odds ratios of low intake (<1 time/d) of fruit or vegetables for each infant feeding practice. Setting: Japan. Subjects: Japanese mother-child pairs (n 763) from a prospective birth cohort study. Results: Neither breast-feeding duration nor age at introduction of solid foods was associated with fruit intake at 16-24 months of age. Breast-feeding duration, but not age at introduction of solid foods, was associated with later intake of vegetables. When breast-feeding duration was categorized into two groups with the cut-off at 6 months, children who were breast-fed for ≥6 months had a significantly decreased risk of low intake of vegetables (OR = 0·53; 95 % CI 0·34, 0·84) than those breast-fed for <6 months. This association was independent of potential confounders including maternal education and maternal vegetable intake (OR = 0·59; 95 % CI 0·36, 0·97). Conclusions: This finding suggests that ≥6 months of breast-feeding may prevent low intake of vegetables in early childhood among Japanese toddlers.
