Association between parents' work hours and nutrient inadequacy in Japanese schoolchildren on weekdays and weekends

[Socioeconomic and sociodemographic determinants associated with fruit and vegetable consumption among mothers and homes of schoolchildren in Jalisco]

INTRODUCTION

increasing fruit and vegetable consumption is a priority. It has been prioritized as a fundamental objective of public policies worldwide. Given that such consumption in schoolchildren in Jalisco (Mexico) is below the dietary recommendations it is crucial to identify the determinants that influence this consumption to promote the development of contextualized actions that improve it.

OBJECTIVE

to identify the socioeconomic and sociodemographic determinants of fruit and vegetable consumption among mothers and households of schoolchildren in Jalisco, Mexico.

METHOD

an analytical, cross-sectional study carried out during the first quarter of 2020. A validated food consumption frequency and a questionnaire on sociodemographic and socioeconomic factors were used for its development.

RESULTS

a lower educational level of the mothers of schoolchildren was associated with a lower consumption of vegetables by schoolchildren. In turn, a lower household income level was associated with a lower consumption of fruits in schoolchildren.

CONCLUSIONS

a low educational level of mothers and a low household income were determinants associated with fruit and vegetable consumption in schoolchildren. However, there were differences in the determinants for fruits and vegetables. It is essential to consider these factors and their differences in order to plan actions that contribute to improving fruit and vegetable intake in the school population.

Association of Hours of Paid Work with Dietary Intake and Quality in Japanese Married Women: A Cross-Sectional Study

This study investigated the association of hours of paid work with dietary intake and diet quality among Japanese married women. This cross-sectional study was a secondary analysis of a nationwide population survey in 2013. The analytic sample included 644 married women aged 20–59 years. The participants were categorized into five groups according to hours of paid work per week: 0 (housewives), 1–14, 15–34, 35–42, and ≥43 h. Dietary intake was assessed by a self-administered diet history questionnaire. The Nutrient-Rich Food Index 9.3 (NRF9.3) was used to measure the dietary quality. The association of hours of paid work with dietary intake and NRF9.3 score was assessed using a multivariable general linear regression analysis with adjustments for confounders. Hours of paid work were associated with a higher intake of rice and lower intake of vegetables, potatoes, soy products, and seaweeds and nutrients including protein, dietary fiber, and most vitamins and minerals. Hours of paid work were negatively associated with the NRF9.3 score. This study showed that Japanese married women engaging in paid work, especially those who work long hours, have less healthy diets. Efforts to improve the dietary intake of married women with paid work might be needed.

Usual Dietary Intake, Nutritional Adequacy and Food Sources of Calcium, Phosphorus, Magnesium and Vitamin D of Spanish Children Aged One to <10 Years. Findings from the EsNuPI Study

Bone problems in the population begin to be establish in childhood. The present study aims to assess the usual calcium, phosphorus, magnesium, and vitamin D intakes, along with the food sources of these nutrients, in Spanish children participating in the EsNuPI (Estudio Nutricional en Población Infantil Española) study. Two 24 h dietary recalls were applied to 1448 children (1 to <10 years) divided into two sub-samples: one reference sample (RS) of the general population [n = 707] and another sample which exclusively included children consuming enriched or fortified milks, here called "adapted milks" (AMS) [n = 741]. Estimation of the usual intake shows that nutrient intake increased with age for all nutrients except vitamin D. Using as reference the Dietary Reference Values from the European Food Safety Authority (EFSA), calcium and magnesium intakes were found to be below the average requirement (AR) and adequate intake (AI), respectively, in a considerable percentage of children. Furthermore, phosphorus exceeded the AI in 100% of individuals and vitamin D was lower than the AI in almost all children studied. The results were very similar when considering only plausible reporters. When analyzing the food sources of the nutrients studied, milk and dairy products contributed the most to calcium, phosphorus, magnesium, and vitamin D. Other sources of calcium were cereals and vegetables; for phosphorus: meat, meat products, and cereals; for magnesium: cereals and fruits; and, for vitamin D: fish and eggs. These results highlight the desirability of improving the intake concerning these nutrients, which are involved in bone and metabolic health in children. The AMS group appeared to contribute better to the adequacy of those nutrients than the RS group, but both still need further improvement. Of special interest are the results of vitamin D intakes, which were significantly higher in the AMS group (although still below the AI), independent of age.
