AIMS: To explore the risk factors of nocturia in Chinese inhabitants aged ≥40 years.
METHODS: A randomized, community-based, cross-sectional study was performed on 10,160 inhabitants ≥40 years old in mainland China, via a stratified sampling approach. A questionnaire, including socio-demographics, lifestyle factors and medical history, was completed. Nocturia was defined as a threshold of two or more voids per night. Differences in prevalence between age and gender groups were ascertained by the chi-squared test. Gender-related factors were evaluated by multivariate logistic regression analysis. P < 0.05 was considered to be statistically significant.
RESULTS: Data on 9,637 (94.9%) people aged 59.6 ± 9.7 years qualified for final statistical analysis. The overall prevalence of nocturia was 31.7% (3,053/9,637), and this increased with age (P < 0.001). Nocturia was significantly associated with cardiovascular disease and overactive bladder symptom score (OABSS) (P < 0.05), while sporting activities were protective (P < 0.001). Diabetes mellitus (DM) was significantly correlated with nocturia in men (P < 0.05), whereas hypertension was correlated with nocturia in women (P < 0.05). No correlation was found between nocturia and education level, occupation, civil status, tea consumption, body mass index (BMI), female birth history, and International Prostate Symptom Score.
CONCLUSIONS: In Chinese people aged ≥40 years, nocturia is associated with aging, OABSS, cardiovascular disease, hypertension, and DM. Sporting activities are negatively associated with nocturia.
