“…A 2008 Pregnancy Risk Assessment Monitoring System (PRAMS) study found that only 13% of women in the US reported engaging in 30 or more minutes of PA on five or more days per week before pregnancy [15]. Another cross-sectional Canadian study of women planning to conceive found that more than half (57.7%) did not meet the recommended PA [16]. Furthermore, despite contrary belief, data from a study involving 12,391 Australian women of reproductive age, both with and without pregnancy intentions, revealed that they do not necessarily change their behaviour before pregnancy [17].…”

Engaging in regular preconception physical activity (PA) is associated with benefits, including improved cardiovascular health and mental well-being. However, most women do not meet PA recommendations in the preconception period. This study aimed to investigate enablers and barriers related to PA in preconception women using a sequential mixed method design. An online survey was followed by Zoom interviews with women of reproductive age (aged 18–45 years). A weaving approach and the Capability Opportunity Motivation Behaviour (COM-B) model were used to integrate and present the data. Seven hundred and eighty-eight non-pregnant women from Australia, India, and the US completed the quantitative survey, and 13 Australian-based women participated in a qualitative interview. Physical activity levels were associated with having social support, a desire to improve body image, and becoming a healthier person. Women encountered barriers such as misconceptions about PA, competing priorities, financial constraints, and a lack of accessibility. Enablers for participation in PA included knowledge of its importance, a desire to be healthier, weight loss, social support, and having goals. The multifaceted and intricate nature of enablers and barriers for preconception PA lays the groundwork for developing tailored interventions and policies aimed at promoting preconception PA among women.

Background The dietary glycemic index (GI) and load (GL) reflect carbohydrate quality and quantity, potentially impacting fertility through modulation of insulin sensitivity and generation of oxidative stress. While fertility is influenced by both women and men, reproductive research often emphasizes maternal factors. We first examined periconception dietary intake in both women and male partners, and subsequent associations of dietary GI and GL with fecundability and subfertility. Methods Among 830 women and 651 male partners, participating in a population-based prospective cohort study from preconception onwards, we assessed periconception dietary intake and calculated GI and GL, using a food frequency questionnaire (FFQ) at median 12.4 weeks gestation (95% range 10.9, 18.4). Information on time to pregnancy was obtained through questionnaires, with subfertility defined as a time to pregnancy ≥ 12 months or use of assisted reproductive technology. Results In the periconception period, mean energy intake in women was 1870 kcal (SD: 500; 46% carbohydrates, 16% protein, 33% fat; dietary GI 56.2 (SD: 3.5) and GL 141.4 (SD: 67.4)). Mean energy intake in men was 2350 kcal (SD: 591; 43% carbohydrates, 16% protein, 33% fat; dietary GI 56.8 (SD: 3.2) and GL 156.7 (SD: 75.4)). Median time to pregnancy was 4.8 months (IQR: 1.2, 16.4), with 30.6% of 830 women experiencing subfertility. Dietary GI and GL were not associated with fertility outcomes in women. In men, higher dietary GI and GL across the full range were associated with decreased fecundability, after adjusting for socio-demographic and lifestyle factors, as well as dietary GI or GL of female partners [FR: 0.91, 95% CI 0.83, 0.99; FR: 0.90, 95% CI 0.81, 0.99, per SDS increase in dietary GI and GL, respectively]. When assessing the combined influence of dietary GI clinical categories in women and men, both partners adhering to a low GI diet tended to be associated with increased fecundability, but not with subfertility risk. Conclusions Suboptimal periconception carbohydrate intake may be negatively associated with male fertility, but not with fertility outcomes in women. Further studies are needed to assess whether a lower GI and GL diet is a feasible lifestyle intervention to improve couples fertility.
