The aim of the study was to examine the effect of the introduction of a new food-support benefit 'Healthy Start' (HS) on dietary intakes and eating patterns of low-income, Caucasian, pregnant and postpartum women living in Sheffield (UK). A before-and-after study comparing nutritional behaviour of participants, who were beneficiaries or eligible for the Welfare Food Scheme (WFS) (phase 1) or HS (phase 2), was conducted. Dietary intakes and eating patterns were assessed using a validated semi-quantified FFQ. In phase 1, 176 WFS subjects (ninety pregnant and eighty-six postpartum) were recruited and in phase 2, there were 160 HS subjects (ninety-six pregnant and sixty-four postpartum). The results suggested that pregnant and postpartum HS women significantly increased their daily intakes of energy, Fe, Ca, folate and vitamin C compared with the WFS women. Observed differences remained significant after controlling for potential confounding effects of known factors, i.e. education and age. HS women were more likely to meet the recommended nutrient intakes for Fe, folate, Ca and vitamin C. HS women ate significantly more mean portions of fruit and vegetables per d (P = 0.004 and P = 0.023) respectively. None of the HS recipients was receiving HS vitamin supplements. The present study showed that pregnant and postpartum HS women increased their food consumption, and a higher proportion of them than the earlier WFS scheme met the recommended intakes for Ca, folate, Fe and vitamin C.
本研究的目的是调查一项新的食品支持福利项目“健康开端”(HS)对居住在英国谢菲尔德的低收入、白人、孕期及产后女性的饮食摄入量和饮食模式的影响。开展了一项前后对照研究,比较了受益于或符合福利食品计划(WFS)(第一阶段)或HS(第二阶段)的参与者的营养行为。使用经过验证的半定量食物频率问卷评估饮食摄入量和饮食模式。在第一阶段,招募了176名WFS受试者(90名孕妇和86名产后女性),在第二阶段,有160名HS受试者(96名孕妇和64名产后女性)。结果表明,与WFS女性相比,孕期及产后的HS女性显著增加了能量、铁、钙、叶酸和维生素C的每日摄入量。在控制了已知因素(即教育程度和年龄)的潜在混杂效应后,观察到的差异仍然显著。HS女性更有可能达到铁、叶酸、钙和维生素C的推荐营养素摄入量。HS女性每天食用的水果和蔬菜平均份数显著更多(分别为P = 0.004和P = 0.023)。没有一名HS受益者正在接受HS维生素补充剂。本研究表明,孕期及产后的HS女性增加了食物摄入量,与早期的WFS计划相比,她们中更高比例的人达到了钙、叶酸、铁和维生素C的推荐摄入量。
