Special Issue Information

Dear Colleagues,

Overweight and obesity represents a public health crisis. Worldwide, over half of adults are overweight or obese, a rate that is continuing to rise. Maternal overweight and obesity affects up to 50% of women in the developed world. Women who are overweight or obese in pregnancy have increased risks of adverse pregnancy outcomes, and contribute to significantly increased healthcare-related costs. The infants born to women who are overweight or obese in pregnancy are more likely to be large for gestational age, and/or macrosomic, be admitted to the special care nursery, and have hypoglycemia requiring treatment.

Increasingly, the intrauterine environment, and antenatal period, is being recognized as playing an important role in both childhood health and illness, and future maternal health. Current estimates suggest almost 1 in 5 children are overweight or obese. Maternal overweight and obesity represents one of the strongest modifiable risk factors for childhood obesity, however, knowledge of the mechanisms underlying this relationship, and evidence-based interventions for preventing this intergenerational cycle of obesity are lacking.

We invite authors to submit articles to this Special Issue on diet, adiposity, and metabolic health in pregnancy. The aim of this issue is to highlight:

  • Effects of diet, adiposity, and metabolic health, on pregnancy outcomes and offspring and maternal future health
  • Causal mechanisms underlying the effects of maternal overweight and obesity and metabolic health on pregnancy outcomes, and
  • Interventions and health promotion aimed at improving maternal diet and metabolic health at a population level

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Environmental Research and Public Health is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2500 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Evidence has established that a cadence of 100 steps/min is indicative of the moderate intensity threshold of 3 metabolic equivalents (METs), but this has only been described in non-pregnant individuals. As metabolic alterations are well established during pregnancy, the purpose of this study was to determine if the walking cadence equivalent to 3 METs in pregnant women is similar to non-pregnant populations. Pregnant females (n = 29; age = 30.3 ± 3.2 years, gestational age = 23.9 ± 6.6 weeks) in their second or third trimester (>12 weeks gestation) completed three stages of treadmill walking for 5 min at different standardized walking speeds: 2.5, 3.0, and 3.5 miles per hour (mph). Oxygen consumption (VO2) and heart rate (HR) were measured each minute and METs were calculated for each stage. Real-time continuous monitoring of walking cadence was evaluated by an OptoGait gait analysis system. Following the three standardized speed stages, participants completed an additional stage walking at a speed that elicited 100 steps/min; VO2 and HR were also collected. A one-sample t-test was used to compare MET values at each stage to the heuristic 3 MET cutoff, and Pearson correlation coefficient was calculated to evaluate the relationship between cadence and METs. Mean cadence increased linearly across the three stages (2.5 mph = 103.7 ± 4.5, 3.0 mph = 112.5 ± 5.3, and 3.5 mph = 120.4 ± 6.2 steps/min), as did METs (2.5 mph = 2.7 ± 1.7, 3.0 mph = 3.2 ± 0.8, and 3.5 mph = 4.3 ± 1.8 METs) regardless of trimester. The average treadmill speed at which women walked at 100 steps/min was 2.4 ± 0.4 mph which elicited an oxygen consumption of 9.5 mL•kg−1•min−1, or 2.7 ± 0.7 METs. There was no significant difference between METs at 3.0 mph and the conventional 3 MET cut point for moderate-intensity PA (p < 0.05). There was a moderate and significant relationship between METs and cadence (2nd trimester: r = 0.51; 3rd trimester: r = 0.42). Current data indicate for the first time that the traditionally used 3 MET cutoff for moderate-intensity activity is appropriate for pregnant women despite metabolic alterations associated with pregnancy. This may have important implications for exercise prescription in pregnant populations. Full article
