Factor analysis of defecation status in the general elderly population: the Yamagata Cohort Study.

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
backgroundThe prevalence of constipation is increasing with the aging of the population, significantly impacting the quality of life in older adults. However, a comprehensive analysis of the physical, psychological, and social correlates of constipation in Japan remains limited. This study aimed to examine factors associated with defecation status in community-dwelling older adults in Japan.
methodsWe conducted a cross-sectional analysis of 8,009 community-dwelling residents aged 65 years and older who completed the baseline health and lifestyle questionnaire as part of the Yamagata Cohort Study. Constipation was defined as fewer than three bowel movements per week. Physical, psychological, and social factors were assessed using self-administered questionnaires. Associations with constipation were examined using chi-square tests and multivariable logistic regression, including sex-stratified models.
resultsConstipation was observed in 407 participants (5.1%). In the multivariable analysis, it was significantly associated with being female (odds ratio [OR] = 1.26, 95% confidence interval [CI]: 1.02-1.56; reference: male), having a body mass index (BMI) ≥25 kg/m
conclusionConstipation in community-dwelling older adults in Japan was associated with multiple physical, psychological, and social factors, with sex-specific differences. Given the cross-sectional design, causality cannot be inferred. These findings suggest that constipation in older adults may be associated with a complex interplay of physical, psychological, and social factors, highlighting the need for comprehensive and integrated approaches in community settings. Integrated geriatric care that addresses these dimensions may be effective in preventing and managing constipation in this population.
