“…A possible explanation for the observed association may be in conformance with previously suggested hypotheses [26]. Of note, NHPM contain higher amounts of saturated fats, which possibly contribute to infertility and pregnancy loss [20].…”

“…To the best of our knowledge, this study is the first to report that the frequency of NHPM consumption was associated with a higher likelihood of infer-tility. Previous research has investigated the relationship between pre-pregnancy nutrition and time to pregnancy and infertility [26]. A study by Grieger et al [26], including a total of 5628 nulliparous pregnant women, retrospectively collected data on self-reported time to pregnancy and preconception dietary intake, in terms of the frequency of fast food, fruit, vegetable, and fish intake 1 month prior to conception.…”

The results shed light on the importance of eating a good-quality diet, specifically including regular intake of fruits, and minimizing fast food consumption for improving fecundity.…”

The purpose of this study was to determine whether eating non-home-prepared meals (NHPM), including fast food, readyto-eat foods, and frozen foods, was associated with self-reported infertility in the United States women. Methods: Data on diet and infertility from women aged 20-49 years who participated in the 2013-2014 and 2015-2016 National Health and Nutrition Examination Surveys were analyzed (n=2143). Dietary information, including the number and types of NHPM consumed, was obtained from a self-reported questionnaire, and infertility status was analyzed using the following question, "Have you ever attempted to become pregnant over a period of at least a year without becoming pregnant?" Results: The frequency of NHPM consumption was positively associated with self-reported infertility after adjusting for confounding effects (odds ratio [OR], 2.82; 95% confidence interval [CI], 1.48 to 5.38 of >1 vs. 0 NHPM/d). The odds of infertility were 2-3 times higher in women who consumed fast food than in those who did not consume fast food (OR, 2.73; 95% CI, 1.15 to 6.48 of >1 vs. 0 times/d). Conclusions: The frequency and types of NHPM may be a factor contributing to infertility. Although our findings require confirmation, they suggest that eating out may be deleterious to women fecundity.

“…Retrospectively reported data at this same visit was also obtained: cigarette use and any intake of alcohol per week in the 3 months pre‐pregnancy were binary coded as yes or no. Number of servings of fruit (fresh fruit and fruit juice), green leafy vegetables (vegetables high in folate such as spinach, cabbage, lettuce, and broccoli), fish (with prompts of fish such as salmon, trout, sardines, shellfish, and shrimp), and ‘fast food’ (frequency of intake of burgers, fried chicken, pizza, and hot chips) have been described previously . Paternal data, including paternal age, and paternal height and weight (to calculate BMI), was self‐reported from the biological father at the first (14–16 weeks of gestation) or second (19–21 weeks of gestation) antenatal visit, or after the baby was born.…”

Objective To determine: (1) the association between metabolic syndrome (MetS), time to pregnancy (TTP), and infertility; (2) associations between individual and an increasing number of MetS components, TTP, and infertility; and (3) whether these relationships differ by body mass index (BMI < 30 kg/m2 versus BMI ≥ 30 kg/m2). Design Retrospective cohort study. Setting Multiple centres (in Australia, Ireland, New Zealand, and the UK). Population Five thousand five hundred and nineteen low‐risk nulliparous pregnant women. Methods Data on retrospectively reported TTP (number of months to conceive) and a blood sample to assess metabolic health were collected between 14 and 16 weeks of gestation. MetS was defined according to the International Diabetes Federation criteria. Accelerated failure time models with log‐normal distribution were conducted to estimate time ratios (TRs) and 95% CIs. Differences in MetS on infertility (TTP > 12 months) were compared using a generalised linear model (Poisson distribution) with robust variance estimates (relative risks, RRs; 95% CIs). All analyses (entire cohort and split by BMI) were controlled for a range of maternal and paternal confounding factors. Main outcome measures Time to pregnancy and infertility. Results Of the 5519 women included, 12.4% (n = 684) had MetS. Compared with women without MetS, women with MetS had a longer TTP (adjusted TR 1.30; 95% CI 1.15–1.46), which was similar in women who were obese and in women who were not obese. Marginal estimates for median TTP in women with MetS versus without MetS was 3.1 months (3.0–3.3 months) versus 4.1 months (3.6–4.5 months), respectively. Women with MetS were at a 62% greater risk for infertility and were at a greater risk for infertility whether they were obese (adjusted RR 1.62; 95% CI 1.15–2.29) or not (adjusted RR 1.73; 95% CI 1.33–2.23). Reduced high‐density lipoprotein cholesterol (HDL‐C) and raised triglycerides (TGs) were the main individual components associated with risk for infertility. Conclusion Metabolic syndrome is associated with longer TTP and infertility, independent of obesity. Additional studies, before pregnancy, are required to support our findings and to determine the applicability of which combinations of metabolic abnormalities pose the greatest risk to delayed fertility, or whether individual components are amenable to modification. Tweetable abstract Metabolic syndrome is associated with longer time to pregnancy and infertility, independent of obesity.
