Physical activities and cardiometabolic profiles of African overweight and obese pregnant women.
Article in BMC pregnancy and childbirth, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPregnancy triggers physiological adjustments through hormonal changes, supporting foetal growth and preparation for labour. Becoming more pronounced with excessive weight, these changes may trigger pathophysiological changes and unmask pre-existing disease conditions. In developing countries, many pregnant women experience either inadequate or excessive weight gain and may present with perturbed metabolism. Lifestyle interventions, including regular physical activity, are important but often overlooked in these settings. Context-specific data on physical activity and cardiometabolic profile of overweight and obese pregnant women are limited in sub-Saharan Africa, specifically Tanzania. The current analysis aimed to determine the relationship between pre-pregnancy overweight/obesity, pregnancy physical activity and cardiometabolic factors among pregnant women.
methodsThis cross-sectional study involving 243 pregnant women aged 18-35 was conducted in selected antenatal clinics in Dodoma, of whom 37% (n = 91) were overweight or obese. The current analysis assessed physical activity, anthropometric, and cardiometabolic parameters and compared between overweight/obese and normal-weight participants.
resultsOverweight and obese pregnant women demonstrated significantly lower levels of physical activity across various domains, including overall physical activity (p < 0.001) and median METs (metabolic equivalent of tasks) minutes per week (p < 0.001) compared with their normal weight counterparts. In particular, they had lower median METs obtained from the occupational domain (p = 0.037). Additionally, the same group engaged less in exercise or leisure time physical activities (p = 0.014), with a lower percentage of contribution to total METs minutes per week obtained from these activities (p = 0.002). Furthermore, overweight or obese participants exhibited higher systolic blood pressure (p < 0.001), diastolic blood pressure (p = 0.008), haemoglobin levels (p < 0.001), fasting blood glucose levels (p = 0.005), serum triglycerides levels (p = 0.012), and total cholesterol levels (t(234) = 1.98, p = 0.048) than their normal-weight counterparts. CONCLUSION AND RECOMMENDATIONS: Overweight and obese pregnant women showed lower physical activity levels, with low levels of both occupational and leisure time (exercise) physical activities, possibly explaining the observed cardio metabolic perturbation in this group. An intervention aiming at promoting physical activity and enhancing cardiometabolic health among this group is necessary.
