Deep health: A qualitative, woman-centered perspective of health during pregnancy

OBJECTIVE

To explore and define a woman-centered perspective on health during pregnancy.

DESIGN

Qualitative study using abductive thematic analysis of semi-structured interview data.

SETTING & PARTICIPANTS

Twenty pregnant participants, primarily single and low-income, were recruited from an urban women's health clinic in the Midwestern United States and interviewed during mid-to-late pregnancy.

FINDINGS

Women experienced health as "deeper than physical health" to include emotional well-being, financial stability, and support. We defined the central theme of Deep Health to be an embodied sense of happiness, energy, stability, and purpose (Being) supported through positive health practices (Doing) and adequate financial and social resources (Having).

KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

While the Doing aspects of health are often a focal point for health promotion efforts in prenatal care, a restricted focus on lifestyle behaviors may contribute to a lack of shared understanding about health between women and their healthcare providers. Greater attention to the Being and Having aspects of health may work to bolster shared priorities for health between pregnant women and their providers.

Pregnancy as a Fundamental Determinant of Child Health: a Review

PURPOSE OF REVIEW

Maternal conditions and exposures during pregnancy including over- and undernutrition are associated with poor childbirth outcomes, growth, development and chronic childhood diseases. We examined contemporary pregnancy-related determinants of child health.

RECENT FINDINGS

While maternal undernutrition remains a major contributor to low birth weight, maternal obesity affects foetal growth, birth weight, survival and is associated with childhood obesity, asthma and autistic spectrum disorders. Emerging evidence suggests that epigenetic changes, the prenatal microbiome and maternal immune activation (MIA), a neuroinflammatory process induced by diet and other exposures cause foetal programming resulting in these chronic childhood diseases. Maternal diet is potentially a modifiable risk factor for controlling low birth weight, obesity and chronic disease in childhood. Further studies are warranted to refine guidance on dietary restriction and physical activity during pregnancy and determine how MIA and prenatal microbiota can be applied to control childhood diseases arising from programming.

Be Healthy in Pregnancy (BHIP): A Randomized Controlled Trial of Nutrition and Exercise Intervention from Early Pregnancy to Achieve Recommended Gestational Weight Gain

A randomized two-arm prospective superiority trial tested the efficacy of a novel structured and monitored nutrition (bi-weekly counselling for individualized energy and high dairy protein diet) and exercise program (walking goal of 10,000 steps/day) (intervention) compared to usual care (control) in pregnant women to achieve gestational weight gain (GWG) within current recommendations. Women recruited in communities in southern Ontario, Canada were randomized at 12–17 weeks gestation with stratification by site and pre-pregnancy BMI to intervention (n = 119) or control (n = 122). The primary outcome was the proportion of women who achieved GWG within the Institute of Medicine recommendations. Although the intervention compared to control group was more likely to achieve GWG within recommendations (OR = 1.51; 95% CI (0.81, 2.80)) and total GWG was lower by 1.45 kg (95% CI: (−11.9, 8.88)) neither reached statistical significance. The intervention group achieved significantly higher protein intake at 26–28 week (mean difference (MD); 15.0 g/day; 95% CI (8.1, 21.9)) and 36–38 week gestation (MD = 15.2 g/day; 95% CI (9.4, 21.1)) and higher healthy diet scores (22.5 ± 6.9 vs. 18.7 ± 8.5, p < 0.005) but step counts were similar averaging 6335 steps/day. Pregnancy and infant birth outcomes were similar between groups. While the structured and monitored nutrition with counselling improved diet quality and protein intake and may have benefited GWG, the exercise goal of 10,000 steps/day was unachievable. The results can inform future recommendations for diet and physical activity in pregnancy.

Maternal and Early-Life Nutrition and Health

Nutritional challenges prior to and during gestation, lactation, and early life are known to influence the lifelong health of the infant. In this editorial, I briefly discuss the 13 articles published in this Special Issue, “Maternal and Early-Life Nutrition and Health”. This Special Issue discusses topics including maternal nutrition behaviors, maternal overnutrition/obesity, maternal iron deficiency, breastfeeding, and others. This issue paves the way to better understand perinatal nutrition and how it can impact maternal and offspring health.
