Prevalence of obesity and its associated factors among healthcare workers in Malaysia: a scoping review.
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
objectivesThis scoping review sought to consolidate Malaysian research on excess body weight among healthcare workers by (i) mapping published prevalence estimates of overweight and obesity, and (ii) describing reported associated risk factors within four domains: sociodemographic and occupational, behavioural, psychosocial, and anthropometric.
methodsPubMed, Scopus, and Web of Science (WoS) were searched for records published between January 2000 and July 2025. Empirical reports and completed systematic reviews that presented prevalence estimates or determinants of overweight or obesity among Malaysian healthcare workers were eligible. Eight studies met these criteria. Data on study setting, sample size, diagnostic thresholds for body mass index (BMI), prevalence, and effect sizes for risk factors were extracted and organised thematically. No meta-analysis was attempted because of methodological heterogeneity.
resultsAcross eight studies, combined overweight plus obesity prevalence ranged from 21.0% to 55.9%, consistently exceeding the national adult averages. Nursing, support, and administrative staff recorded the highest levels; one screening study showed that 63.0% to 100.0% of these staff categories were above the healthy weight range. Individual aged 40 years and older, employment duration of at least five years, and nurse job title each increased the likelihood of obesity by roughly twofold. Low physical activity, meal skipping, sugared-drink intake and restrained eating style was reported in three studies, while depressive symptoms and short sleep was linked to higher weight. Two reports documented clustering of central adiposity with elevated blood pressure in younger nurses.
conclusionsMalaysian healthcare facilities were found to be as obesogenic workplaces, particularly for long-serving nursing, support, and administrative staff. Interventions should combine specific schedule reforms, healthy food access, movement-promoting design and integrated mental health support. These programmes should be evaluated using longitudinal metrics of body mass and cardiometabolic health.
