    Food Group Consumption and Nutrient Intake by Breastfeeding Women: Comparison to Current Dietary Guidelines and Nutrient Recommendations.
    (MDPI (Basel, Switzerland), 2025-01-21) Jin Y; Coad J; Brough L; Billeaud C; Asher O
    BACKGROUND/OBJECTIVES: Optimal nutrition is essential for the health of breastfeeding women and their infants. This study aimed to assess food and nutrient intake and alignment with nutrition guidelines for breastfeeding women living in New Zealand. METHODS: Seventy-six breastfeeding women were enrolled in the longitudinal Mother and Infant Nutrition Investigation study and completed a weighed four-day diet diary including supplement use at three months postpartum. The number of servings consumed for each food group were calculated based on the 2020 Eating and Activity Guidelines for New Zealand Adults. Nutrient intakes were compared to the nutrient reference values for Australia and New Zealand. RESULTS: Overall, the percentages of women who met the recommended number of servings for fruits, vegetables, grain foods, meats and milk/milk products were 25%, 0%, 5%, 34%, and 13%, respectively. None of women met the current recommendations for all food groups. Many participants had intakes below the estimated average requirement or adequate intake and were at risk of nutrient inadequacy for vitamin E (55%), vitamin D (53%), manganese (61%), and selenium (55%). CONCLUSIONS: Breastfeeding women had a low alignment with the current dietary guidelines and were at risk of an inadequate intake of vitamin E, D, manganese, and selenium. Research to investigate the barriers and enablers of healthy food choices is needed.

    Perinatal mental health and women's lived experience of the COVID-19 pandemic: A scoping review of the qualitative literature 2020-2021.
    (Elsevier B.V., 2023-05-09) Jin Y; Murray L
    BACKGROUND: The COVID-19 pandemic resulted in global physical distancing restrictions and lockdown orders. Despite the clear documentation of increased mental distress amongst adult populations during the pandemic, there is limited evidence about the mental health challenges of people in the perinatal period (pregnancy, birth and postpartum). The aim of this review is to summarise the qualitative research about women's lived experience and emotional wellbeing during the COVID-19 pandemic. METHODS: A comprehensive search strategy was developed. Twenty peer-reviewed qualitative research articles published in English from January 1, 2020, to December 15, 2021, were included. Data synthesis outlined the evidence from common themes in a narrative format. RESULTS: Themes during pregnancy included: (1) information seeking: anxiety and fear; (2) experiencing isolation and disruptions to my social support; (3) 'Going it alone' in pregnancy care; (4) anticipatory grieving and despair; (5) finding 'silver linings' in social restrictions. One key theme during birth was "birthing in a crisis". Themes during postpartum included: (1) isolating 'Early motherhood is much like lockdown'; (2) breastfeeding: triumphs and tribulations; (3) facing disruptions during postpartum care; (4) 'Affecting us for years to come' - COVID-19 was not the only trauma; (5) 'silver linings' during postpartum care. CONCLUSIONS: This review provides important insights into how experiences of isolation, decreased social support and adaptions to maternity services affect women's mental health. Maternity services should consider how perinatal mental health support may be integrated into the care of women who may still be required to isolate or have reduced visitors during their perinatal care. STATEMENT OF SIGNIFICANCE: The restrictions and disruptions to maternity care due to the COVID-19 pandemic were likely to impact the mental health of women in the perinatal period (pregnancy, birth and postpartum). What is already known is that public health measures due to COVID-19 increased the prevalence of common perinatal mental disorders (CPMDs) and exacerbated common risk factors for CPMDs (i.e., poor social support). WHAT THIS PAPER ADDS: The qualitative research with women in the perinatal period during the pandemic provides unique insights into how these events impacted perinatal mental and emotional health. In particular, the ways that global physical distancing measures and maternity care adaptations contributed to women's feelings of distress, isolation, and depression/despair. Silver linings such as more uninterrupted time with immediate family were also identified.

    Portable X-ray fluorescence of zinc and selenium with nail clippings-Mother and Infant Nutrition Investigation (MINI).

    Zinc and selenium are essential minerals for human nutrition. Reliable biomarkers of zinc status and selenium status in humans are therefore important. This work investigates a novel portable X-ray fluorescence (XRF) method with the ability to rapidly assess zinc and selenium in nail clippings. This approach used a mono-energetic X-ray beam to excite characteristic X-rays from the clippings. Nail clippings were obtained from the Mother and Infant Nutrition Investigation (MINI), a study designed to assess nutrition in a population of women and their breastfed children in New Zealand. Twenty mother-infant pairings were selected to provide nail clippings at two time points (visit 1 at 3 months postpartum; visit 2 at 6 months postpartum). Nail clippings from each mother-infant pairing were divided into three groupings of clippings prior to analysis: those obtained from a big toe of the mother, those from the other toes of the mother, and those from the toes and fingers of the infant. Clippings were prepared and mounted prior to XRF measurement, providing four distinct fragments from each clipping grouping. These fragments were assessed by XRF using a measurement time of either 300 s (visit 1) or 180 s (visit 2). XRF results were determined through both an automated system output and an analysis of the X-ray energy spectrum. Following this assessment of zinc and selenium with the non-destructive XRF method, clippings were measured for zinc and selenium concentration using a "gold standard" technique of inductively coupled plasma mass spectrometry (ICP-MS). Mean ICP-MS concentrations ranged from 122 μg/g to 127 μg/g for zinc, and from 0.646 μg/g to 0.659 μg/g for selenium. Precision, assessed by a relative standard deviation of measurement, was superior for ICP-MS relative to XRF. For both zinc and selenium, XRF results were compared with ICP-MS concentrations. Linear equations of best fit were determined for each comparison between XRF and ICP-MS results. Coefficients of determination (r2) were stronger for zinc (from 0.74 to 0.95) than selenium (from 0.53 to 0.70). A decrease in XRF measurement time from 300 s to 180 s did not appear to adversely affect the correlation between XRF and ICP-MS results. Using the mono-energetic portable XRF method, the correlation of XRF zinc results with ICP-MS zinc concentrations was improved over previous findings, and selenium measurement was reported for the first time. The method may prove useful for future applications to trace element analysis using nail clippings as a biomarker.
