“…Intake of MUFA and PUFA may be related to the increased BW and reduced risk of LBW (5,12) . Increased maternal haem Fe intake may protect against LBW and SGA (14) . The 107 food items were consolidated into twenty-four food groups (wheat, rice, potatoes, legumes, soyabean products, green vegetables, other vegetables, fungi, fruits, nuts, red meat, poultry, processed meat, dairy products, eggs, fish, snacks, fast food, soft drinks, alcohol drinks, sweets, oils, solid fats and condiments) based on China Food Composition Tables and the logic of intake (32) .…”

Few studies have investigated the association between maternal dietary patterns (DP) during pregnancy, derived from reduced-rank regression (RRR), and fetal growth. This study aims to identify DP during pregnancy associated with macro- and micronutrient intakes, using the RRR method, and to examine their relationship with birth weight (BW). We used data of 7194 women from a large-scale cross-sectional survey in Northwest China. Dietary protein, carbohydrate, haem Fe density and the ratio of PUFA and MUFA:SFA were used as the intermediate variables in the RRR model to extract DP. Generalised estimating equation models were applied to evaluate the associations between DP and BW and related outcomes (including BW z-score, low birth weight (LBW) and small for gestational age (SGA)). Four DP during pregnancy were identified. Socio-demographically disadvantaged pregnant women were more likely to have lower BW and lower adherence to DP1 (high legumes, soyabean products, vegetables and animal-source foods, with relative low wheat and oils). Women with medium and high adherence to DP1 had significantly increased BW (medium 28·6 (95 % CI 7·1, 50·1); high 25·2 (95 % CI 2·7, 47·6)) and BW z-score and had significantly reduced risks of LBW and SGA. The associations were stronger among women with babies <3100 g. There is no association between other DP and outcomes. Higher adherence to the DP that was high in legumes, soyabean products, vegetables and animal-source foods was associated with improved BW in the Chinese pregnant women, particularly among those with disadvantageous socio-demographic conditions.

“…For the micronutrient, increased BW was associated with increasing pantothenic, biotin, Mg, vitamin D and vitamin B 12 intakes (12) . Total Fe intake from food and supplements, prenatal Fe use and the dietary haem Fe intake were also in relation to improved BW and related outcomes such as LBW and SGA (14)(15)(16) .…”

The effect of maternal folate intake on small-for-gestational-age (SGA) births remains inconclusive. The present study aimed to investigate the associations of maternal folate intake from diet and supplements with the risk of SGA births using data from a cross-sectional study in Shaanxi Province of Northwest China. A total of 7307 women who were within 12 months (median 3; 10th–90th percentile 0–7) after delivery were included. Two-level models were adopted to examine the associations of folate (dietary folate, supplemental folic acid and total folate) intake with the risk of SGA births and birth weight Z score, controlling for a minimum set of confounders that were identified in a directed acyclic graph. Results showed that a higher supplemental folic acid intake during the first trimester was negatively associated with the risk of SGA births (≤60 d v. non-use: OR 0·80; 95 % CI 0·66, 0·96; >60 d v. non-use: OR 0·78; 95 % CI 0·65, 0·94; Ptrend = 0·010; per 10-d increase: OR 0·97; 95 % CI 0·95, 0·99). A higher total folate intake during pregnancy was associated with a reduced risk of SGA births (highest tertile v. lowest tertile: OR 0·77; 95 % CI 0·64, 0·94; Ptrend = 0·010; per one-unit increase in the log-transformed value: OR 0·81; 95 % CI 0·69, 0·95). A similar pattern was observed for the birth weight Z score. Our study suggested that folic acid supplementation during the first trimester and a higher total folate intake during pregnancy were associated with a reduced risk of SGA births.

RESUMOEm virtude do pequeno número de estudos que analisam os benefícios de mudanças dietéticas no desenvolvimento da gestação, do parto e da lactação, esta revisão sistemática buscou investigar os efeitos da oferta de suplementação de nutrientes e outras modificações dietéticas, em desfechos desejáveis nos processos de gestação e lactação, bem como na prevenção de desfechos clínicos indesejáveis nos recém-nascidos. Foi estruturada conforme as recomendações Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), resultando na seleção de 11 artigos para comporem os resultados do estudo. Buscaram-se artigos originais, indexados às bases de dados eletrônicas PubMed Central (PMC); Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) e Scientific Eletronic Library Online (SciELO) e publicados entre 2008 e 2018, nos idiomas: português, inglês e espanhol. Os descritores estão listados no Medical Subject Heading (MeSH) -em inglês, e nos Descritores em Ciências da Saúde (DeCS)-em português. Com esse estudo pode-se observar a importância da nutrição durante o período gravídico puerperal e seu impacto na saúde materno-infantil. Nota-se que a qualidade de vida da mãe e, principalmente, a qualidade da sua alimentação são imprescindíveis para um bom desenvolvimento fetal. Sendo assim, a avaliação nutricional completa, com foco em uma intervenção precoce, para correção dos desvios diagnosticados, faz-se essencial durante todo o período gestacional e puerperal.
