Objective To explore the predisposing factors of constipation in the elderly. Methods Random cluster sampling method was used to investigate 1434 cases. The definition of constipation is strictly controlled: elderly people often have dry stools, difficulty defecation, and less than 3 stools per week, except for clear diseases and constipation caused by drugs. Results The total prevalence of constipation in the elderly was 203%, 182% in urban areas, and 23.0% in rural areas. The prevalence rates in urban and rural areas were significantly different (P<0.05). Conclusions The prevalence of constipation in the elderly in rural areas is significantly higher than that in urban areas. The predisposing factors are related to age, gender, and people who are unable to take care of themselves or have self-care in daily life.
