Correlation Between Gestational Weight Gain and Low Back Pain in the Third Trimester: A Cross-Sectional Study.
Article in Journal of pregnancy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
BACKGROUND AND
aimsPregnancy involves physiological changes that may lead to low back pain (LBP), especially in the third trimester. Excessive gestational weight gain (GWG) has been suggested as a contributing factor, but evidence in low-income populations is scarce. This study is aimed at correlating GWG with LBP in the third trimester among postpartum women in São Paulo, Brazil.
methodsThis cross-sectional study included 53 postpartum women (18-42 years of age) from a public hospital in São Paulo. Data on sociodemographics, GWG, and LBP (visual analog scale, and body map) were collected. Statistical tests included t-test, Mann-Whitney, ANOVA, chi-square, and linear regression (α = 0.05, two-sided).
resultsMean age was 28.2 years; 77.3% reported LBP, 53.7% with severe pain (VAS ≥ 6). Mean GWG was 12 kg. Women with severe pain had higher absolute weight gain (14.7 kg vs. 10.3 kg; p = 0.028) but no significant difference in weight progression across trimesters. Linear regression showed no causal relationship between pain intensity and GWG alone (p = 0.463). Manual workers tended to have more severe pain (70.6% vs. 29.4%; p = 0.067).
conclusionLBP was highly prevalent (77.3%) and clinically relevant. Higher absolute GWG was associated with greater pain severity, but no independent causal relationship was found. Multifactorial factors, including occupational demands, may mediate this association. Nutritional monitoring and multidisciplinary prenatal care are recommended.
