There is ongoing debate about the extent to which the epidemiology of OCD is similar across the world, given the lack of nationally representative data from key regions like the Middle East and North Africa. Using the nationally representative dataset from the Saudi National Mental Health Survey (SNMHS), we aimed to delineate the epidemiological profile of OCD in the Saudi population.
A subsample of 1981 participants from the SNMHS was assessed. Prevalence estimates and correlates of OCD were determined using logistic regressions and cross tabulations.
The lifetime, 12-month, and 30-day prevalence estimates for OCD were 4.2%, 1.8%, and 1.6%, respectively, with hoarding being the most common symptom dimension. The mean age-of-onset of OCD was 16.8 years. In over two-thirds of respondents with lifetime (72.2%) or 12-month (71.2%), OCD was accompanied by comorbid mental disorder, particularly impulse control, anxiety, and mood disorders. Among individuals with 12-month OCD, 77.5% reported severe impairment, and only 9.2% received treatment.
In Saudi Arabia, OCD is a prevalent and persistent condition, characterized by early onset, high odds of mental comorbidity, and significant associated impairment. These findings emphasize the universality of OCD epidemiology and the need for improved diagnosis and treatment globally.
鉴于中东和北非等关键地区缺乏全国代表性数据，关于强迫症的流行病学在全球范围内的相似程度仍存在争议。本研究使用沙特全国心理健康调查（SNMHS）的全国代表性数据集，旨在描绘沙特人口中强迫症的流行病学特征。
对 SNMHS 的 1981 名参与者的亚样本进行评估。使用逻辑回归和交叉表确定强迫症的患病率估计值及其相关因素。
强迫症的终生、12 个月和 30 天患病率估计值分别为 4.2%、1.8%和 1.6%，其中囤积是最常见的症状维度。强迫症的平均发病年龄为 16.8 岁。在超过三分之二的终生（72.2%）或 12 个月（71.2%）患有强迫症的患者中，同时伴有共患精神障碍，特别是冲动控制、焦虑和情绪障碍。在 12 个月患有强迫症的个体中，77.5%报告严重受损，只有 9.2%接受了治疗。
在沙特阿拉伯，强迫症是一种普遍且持续存在的疾病，其特征为发病早、精神共病的可能性高以及存在严重的相关损害。这些发现强调了强迫症流行病学的普遍性，以及全球范围内需要改善诊断和治疗的必要性。
