Premature ejaculation (PE) is common. However, it has been underreported and undertreated.
To determine the prevalence of PE and to investigate possible associated factors of PE.
This cross-sectional study was conducted at a primary care clinic over a 3-month period in 2008. Men aged 18-70 years attending the clinic were recruited, and they completed self-administered questionnaires that included the Premature Ejaculation Diagnostic Tool (PEDT), International Index of Erectile Function, sociodemography, lifestyle, and medical illness. The operational definition of PE included PE and probable PE based on the PEDT.
Prevalence of PE.
A total of 207 men were recruited with a response rate of 93.2%. There were 97 (46.9%) Malay, 57 (27.5%) Chinese, and 53 (25.6%) Indian, and their mean age was 46.0 ± 12.7 years. The prevalence of PE was 40.6% (N = 82) (PE: 20.3%, probable PE: 20.3% using PEDT). A significant association was found between ethnicity and PE (Indian 49.1%, Malay 45.4%, and Chinese 24.6%; χ(2) = 8.564, d.f. = 2, P = 0.014). No significant association was found between age and PE. Multivariate analysis showed that erectile dysfunction (adjusted odds ratio [OR] 4.907, 95% confidence interval [CI] 2.271, 10.604), circumcision (adjusted OR 4.881, 95% CI 2.346, 10.153), sexual intercourse ≤5 times in 4 weeks (adjusted OR 3.733, 95% CI 1.847, 7.544), and Indian ethnicity (adjusted OR 3.323, 95% CI 1.489, 7.417) were predictors of PE.
PE might be frequent in men attending primary care clinics. We found that erectile dysfunction, circumcision, Indian ethnicity, and frequency of sexual intercourse of ≤5 times per month were associated with PE. These associations need further confirmation.
早泄（PE）很常见。然而，它的报告和治疗不足。
确定 PE 的流行率，并调查可能与 PE 相关的因素。
这是一项在 2008 年进行的为期 3 个月的初级保健诊所的横断面研究。招募年龄在 18-70 岁之间的男性，他们完成了自我管理的问卷，包括早泄诊断工具（PEDT）、国际勃起功能指数、社会人口统计学、生活方式和医疗疾病。PE 的操作定义包括基于 PEDT 的 PE 和可能的 PE。
PE 的流行率。
共招募了 207 名男性，应答率为 93.2%。其中 97 名（46.9%）是马来人，57 名（27.5%）是中国人，53 名（25.6%）是印度人，平均年龄为 46.0±12.7 岁。PE 的流行率为 40.6%（N=82）（PE：20.3%，使用 PEDT 的可能 PE：20.3%）。发现种族与 PE 之间存在显著关联（印度人 49.1%，马来人 45.4%，中国人 24.6%；χ²=8.564，df=2，P=0.014）。年龄与 PE 之间无显著关联。多变量分析显示勃起功能障碍（调整后的优势比[OR]4.907，95%置信区间[CI]2.271，10.604）、包皮环切（调整后的 OR 4.881，95%CI 2.346，10.153）、4 周内性交次数≤5 次（调整后的 OR 3.733，95%CI 1.847，7.544）和印度裔（调整后的 OR 3.323，95%CI 1.489，7.417）是 PE 的预测因素。
在初级保健诊所就诊的男性中，PE 可能很常见。我们发现勃起功能障碍、包皮环切、印度裔和每月性交次数≤5 次与 PE 相关。这些关联需要进一步证实。
