Factors associated with obesity among female workers in small and cottage industries in Bangladesh: a cross-sectional study.
Article in BMC public health, 2026. 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
backgroundFemales in low- and middle-income countries are vulnerable to obesity due to biological factors such as fat distribution and reproductive physiology and social constraints including limited physical activity and caregiving roles. In Bangladesh, occupational research has largely focused on ready-made garment workers, while females in small and cottage industries such as shrimp processing, handloom, pottery, and nakshi kantha remain underrepresented despite their substantial workforce contribution. This study aimed to estimate the prevalence of obesity among female workers in selected small and cottage industries and to examine occupational, lifestyle, and dietary factors associated with obesity.
methodsA cross-sectional study was conducted between May 2023 and February 2024 among 350 female workers aged 18-60 years across four small and cottage industry sectors (handloom, shrimp farming, pottery, and nakshi kantha) in selected districts of Bangladesh. Study sites were purposively selected to represent major production clusters, and participants were recruited consecutively within sites, limiting generalizability. Data were collected via face-to-face interviews using a semi-structured questionnaire. BMI was measured by trained nutritionists, with obesity defined as ≥ 25 kg/m² (WHO South-East Asia). Associations were examined using chi-square tests and multivariable binary logistic regression analyses with a priori covariate selection, reporting crude odds ratios (COR) and adjusted odds ratios (AOR) with 95% confidence intervals (CIs).
resultsObesity prevalence was 36.0%. In the multivariable analysis, factors significantly associated with obesity included age 31-45 years (AOR 1.979, 95% CI: 1.026-3.819), sedentary work (AOR 2.954, 95% CI: 1.363-6.400), sitting ≥ 8 h/day (AOR 4.233, 95% CI: 2.147-8.346), gastrointestinal complaints (AOR 3.180, 95% CI: 1.237-8.178), physical inactivity (AOR 2.478, 95% CI: 1.131-5.429), screen time ≥ 2 h/day (AOR 3.750, 95% CI: 1.983-7.092), and daily soft drink and energy drink consumption (AOR 2.884, 95% CI: 1.196-6.955). Model fit was acceptable (Hosmer-Lemeshow p = 0.070; Omnibus test p < 0.001; Nagelkerke R² = 0.397).
conclusionsObesity was common and associated with modifiable occupational and lifestyle factors rather than industry type. These findings suggest potential value in workplace-oriented interventions targeting sedentary behavior, physical inactivity, and unhealthy beverage consumption in similar informal work settings.
