The aims of this study were to characterize, among pregnant Mexican women, gestational weight gain (GWG) trajectories; assess associations of maternal dietary quality score (MDQS) with GWG during early-mid pregnancy, middle pregnancy, late pregnancy, and prolonged pregnancy; and evaluate the association between MDQS and adequacy of GWG, throughout pregnancy. We hypothesized that higher MDQS adherence is protective against insufficient or excessive GWG across pregnancy and that the association between MDQS adherence and GWG would vary by prepregnancy body mass index (BMI) category. ⋯ A better quality diet, as measured by MDQS, was associated with appropriate GWG during pregnancy in the PRINCESA cohort.

Although several studies are available that link individual dietary antioxidants to the risk of psychological disorders, data about the association of dietary total antioxidant capacity (TAC) with depression and anxiety are scarce. This study was conducted to investigate the association between dietary TAC and odds of depression and anxiety among Iranian adults. ⋯ We found an significant inverse association between dietary TAC and odds of depression and anxiety among adults. Further prospective studies are required to confirm these findings.

Intrauterine and postnatal micronutrient malnutrition may program metabolic diseases in adulthood. We examined whether moderate zinc restriction in male and female rats throughout fetal life, lactation, or postweaning growth induces alterations in liver, adipose tissue, and intermediate metabolism. ⋯ This study strengthens the importance of a balanced intake of zinc during growth to ensure adequate lipid and carbohydrate metabolism in adult life.

Malnutrition occurs as a complication of hemodialysis (HD) and has been identified as a risk factor for osteoporosis, sarcopenia, and low physical performance. The aim of this study was to assess the associations among nutrition, bone mineral density (BMD), body composition, and handgrip strength (HGS) in patients receiving HD. ⋯ The present study demonstrated that good nutrition, indicated as high GNRI, resulted in higher BMD and T-score, lean mass index, and HGS in patients receiving HD. Using GNRI to evaluate nutritional status and using DXA to investigate BMD and body composition in patients receiving HD is important to bone health and physical performance.

The effects on breast milk composition of advanced maternal age and maternal dietary habits during pregnancy and lactation have not, to our knowledge, been investigated in southeastern Europe and the Balkans. The aim of this study was to compare the content of retinol and β-carotene in colostrum and mature milk samples obtained from different maternal age (MA) groups and to assess the potential relationship with maternal and demographic characteristics, dietary patterns, and lifestyle habits during pregnancy and lactation. ⋯ PCA analysis used in the study clearly confirmed that MA, total lipids, retinol, and β-carotene levels might serve as a good criterion for delimitation of breast milk samples collected in different stages of lactation from mothers of various ages. The present findings could represent key basis for further investigations.
