Unprotected sun exposure could cause tanning, burning, hyperpigmentation, skin aging, and even skin cancer. Regular sunscreen use is a safeguard and a primary preventive strategy against sunlight-related damages. This study aims to find out the prevalence of sunscreen use among medical undergraduate students of a medical college of Eastern Nepal.
A descriptive cross-sectional study was conducted among the current medical undergraduate students of 2 medical colleges in Nepal on sunscreen use from September 2020 to October 2020. Convenience sampling was done to reach the sample size of 300. Data collection was done after taking ethical approval from the Institutional Review Committee (IRC/1778/020). Data analysis was done by using Statistical Package for the Social Sciences version 11.5 software. Point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data.
The prevalence of sunscreen users was found to be 227 (75.67%) (70.81-80.52 at 95% Confidence Interval) among whom only 35 (15.41%) were regular users. Majority 144 (63.43%) applied sunscreen only on the face, 72 (31.71%) considered reapplication, and 155 (68.2%) knew the Sun Protection Factor value of their sunscreen. Cosmetic sunscreen was considered by the majority of the users 151 (66.51%). Greasy feeling 73 (100%) was the reason for avoiding sunscreen use amongst the non-users 73 (24.34%).
The prevalence of sunscreen users among medical undergraduate students from our study was higher than other studies conducted in similar settings.
无保护的阳光照射会导致晒黑、灼伤、色素沉着、皮肤老化，甚至皮肤癌。定期使用防晒霜是防止阳光伤害的一种保障和主要预防策略。本研究旨在了解尼泊尔东部一所医学院校医学生使用防晒霜的情况。
2020 年 9 月至 10 月，我们在尼泊尔的两所医学院校进行了一项横断面描述性研究，调查了医学生使用防晒霜的情况。采用方便抽样法，样本量为 300 人。在获得机构审查委员会（IRC/1778/020）的伦理批准后，进行了数据收集。使用统计软件包 11.5 版进行数据分析。在 95%置信区间内计算了点估计值，以及二项数据的频率和比例。
在 300 名被调查者中，有 227 名（75.67%）（95%置信区间为 70.81-80.52）使用了防晒霜，其中只有 35 名（15.41%）是经常使用者。大多数（63.43%）人只在脸上涂抹防晒霜，72 人（31.71%）认为需要补涂，155 人（68.2%）知道他们防晒霜的防晒因子值。大多数使用者（66.51%）认为防晒霜是化妆品。不使用防晒霜的 73 人（24.34%）认为防晒霜油腻感（100%）是他们避免使用防晒霜的原因。
与在类似环境中进行的其他研究相比，我们的研究中使用防晒霜的医学生比例较高。
