High-quality maternal diets during pregnancy may protect against these adverse birth outcomes.\u0000\u0000\u0000OBJECTIVES\u0000The aim of this study was to prospectively examine the association of maternal dietary diversity and quality during pregnancy with birth outcomes among women in Dar es Salaam, Tanzania.\u0000\u0000\u0000METHODS\u0000We analyzed data from 7553 HIV-negative pregnant women enrolled in a multivitamin trial at 12-27 weeks of gestation. Dietary intake was assessed using 24-h dietary recalls. Dietary diversity scores (DDS; range: 0-10) were computed as the number of food groups consumed by women, using FAO's Minimum Dietary Diversity for Women index. The Prime Diet Quality Score (PDQS; range: 0-42) assessed maternal diet quality based on consumption of 21 healthy and unhealthy food groups. Log binomial regression methods were used to assess associations of DDS and PDQS with PTB, SGA, LBW, and fetal loss.\u0000\u0000\u0000RESULTS\u0000In the previous 24 h, 99.9% of all women had consumed cereal and staples, 57.9% meats, 4.7% eggs, and 0.5% nuts and seeds. Median DDS was 3.0 (IQR: 2.5-3.5). For the PDQS, all women consumed ≥4 servings/wk of green leafy vegetables and refined grains. Higher DDS was associated with lower risk of SGA (RR highest compared with lowest quintile: 0.74; 95% CI: 0.62, 0.89). Higher PDQS was associated with lower risk of PTB (RR highest compared with lowest quintile: 0.55; 95% CI: 0.46, 0.66), LBW (RR: 0.53; 95% CI: 0.40, 0.70), and fetal loss (RR: 0.53; 95% CI, 0.34, 0.82).\u0000\u0000\u0000CONCLUSIONS\u0000PDQS was inversely associated with PTB, LBW, and fetal loss, and DDS was inversely associated with SGA. These findings suggest that in addition to dietary diversity, diet quality should be considered as important in understanding dietary risk factors for poor birth outcomes.This trial was registered at clinicaltrials.gov as NCT00197548.","PeriodicalId":315016,"journal":{"name":"The American journal of clinical nutrition","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130932535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Anthropometry was performed at ages 5, 10, and 16/17 y. At 16/17 y, we determined body composition using DXA and quantified metabolic parameters in a blood sample. We examined the associations of infancy 25(OH)D with BMI-for-age z-score (BMIZ) at ages 5, 10, and 16/17 y; with percentage fat and percentage lean body mass at age 16/17 y; and with a metabolic syndrome (MetS) score and its components at age 16/17 y.\u0000\u0000\u0000RESULTS\u0000Infancy 25(OH)D was inversely associated with BMIZ in childhood.

The studies contained information on dietary nicotine intake from 1986 from validated FFQs. Dietary nicotine intake was calculated based on consumption of peppers, tomatoes, processed tomatoes, potatoes, and tea. Incident cases of PD were identified via questionnaires and subsequently confirmed by reviewing medical records. We used Cox proportional hazard models to calculate cohort-specific HRs, and used fixed-effects models to calculate the pooled HR.\u0000\u0000\u0000RESULTS\u0000During 26 y of follow-up, we identified 601 incident PD cases (296 women and 305 men). After adjusting for potential covariates, the pooled HR for the highest compared with the lowest quintile of dietary nicotine intake was 0.70 (95% CI: 0.51, 0.94).

We conducted a review to summarize the evidence from epidemiologic studies that examined the association of body mass index (BMI), physical activity, and nutrition with colorectal cancer recurrence and survival. We searched MEDLINE and EMBASE for relevant epidemiologic studies published up to March 2010 by using MeSH terms and related key words. We identified 36 articles that were based on 31 independent studies on BMI (n = 21), physical activity (n = 6), or nutrition (n = 12) in relation to colorectal cancer recurrence and survival. Studies were generally based on follow-up of cases in existing patient series, case-control or cohort studies, or chemotherapy trials. BMI, physical activity, and nutrition mostly referred to the time at or before diagnosis. Only 10 studies assessed BMI (n = 1), physical activity (n = 4), or nutrition (n = 5) after diagnosis. There may be an association between higher BMI and body fatness before or at the time of diagnosis and a higher all-cause mortality or colorectal cancer-specific mortality or recurrence, although results may differ by sex, tumor location, and molecular subtype. There may be a relation between higher leisure-time physical activity after diagnosis and a lower all-cause or colorectal cancer-specific mortality. For dietary factors, statistically significant associations were only shown for single foods, nutrients, and dietary patterns in single studies.
