It is essential to understand how we can prevent and treat the epidemic of depression. Several studies have reported the prevalence of depressive symptoms in the urban population in China, but there is a lack of information regarding the prevalence of depression in rural populations.
To understand the prevalence of depression in a rural Chinese population and to analyze the risk factors for depression.
This study used a cross-sectional approach. A total of 11,473 subjects were surveyed and completed the Patient Health Questionnaire-9 (PHQ-9) and the World Health Organization Quality of Life Brief scales. Living conditions, per capita income, marital status, and information about dietary health and chronic disease status were assessed.
The prevalence of depressive symptoms in the population was 5.9%. The prevalence in women (8.1%) was higher compared with men (3.5%) and also increased with age. The per capita income level, amount of sleep obtained per day, education level, weekly consumption of meat and beans or bean products, salt intake, and chronic disease status were associated with depressive symptoms. The quality of life of individuals with a score less than 10 points on the PHQ-9 was significantly better compared with individuals with a score greater than 10.
The prevalence of depressive symptoms among rural population is higher than some southern cities in China. Dietary patterns may be an important risk factor linked to this disorder in the Chinese rural population.
了解如何预防和治疗抑郁症流行至关重要。多项研究报告了中国城市人口中抑郁症状的患病率，但缺乏农村人口抑郁症患病率的相关信息。
了解中国农村人口抑郁症的患病率，并分析抑郁症的危险因素。
本研究采用横断面研究方法。共对11473名受试者进行了调查，他们完成了患者健康问卷-9（PHQ-9）和世界卫生组织生活质量简表。评估了生活条件、人均收入、婚姻状况以及饮食健康和慢性病状况等信息。
该人群中抑郁症状的患病率为5.9%。女性患病率（8.1%）高于男性（3.5%），且随年龄增长而增加。人均收入水平、每日睡眠时间、教育程度、每周肉类和豆类或豆制品的摄入量、盐摄入量以及慢性病状况与抑郁症状相关。PHQ-9得分低于10分的个体的生活质量明显优于得分高于10分的个体。
农村人口中抑郁症状的患病率高于中国一些南方城市。饮食模式可能是中国农村人口中与这种疾病相关的一个重要危险因素。
