背景:
過敏性腸症候群は地域社会では一般的であり、医学生の有病率は高い。
Background: Irritable bowel syndrome is common in the community and its prevalence is higher among the medical students.
研究目的:
本研究では、ジョウフ大学の医学生および非医学生を対象に、過敏性腸症候群の有病率を推定し、その危険因子を評価することを目的とした。
Aim: The current study was carried out to estimate the prevalence and evaluate the risk factors of irritable bowel syndrome among medical and nonmedical students of the Jouf University.
被験者と方法:
本研究は、ジョウフ大学の医学生および非医学生を対象とした横断的研究である。研究の対象は200名の医学生と非医学生である。本研究では、人口統計学的特徴、生活習慣、食生活、学業、過敏性腸症候群の3つのパートからなる自己記入式の質問票を用いた。人口統計学的特徴を示すために記述統計を行った。研究変数間の差を分析するために、カイ二乗検定、95％CI付きオッズ比をSPSS version-16を用いて算出した。IBSの生活習慣と食事の予測因子の多変量解析はEnter法で行った。
Subjects and Methods: This cross-sectional study was carried out among medical and nonmedical students of the Jouf University. Study targeted 200 medical and nonmedical students using the convenience sampling technique. A self-administered questionnaire was adopted for the study and consisted of three parts with questions on demographic characteristics, lifestyle, eating habits, academics, and irritable bowel syndrome. Descriptive statistics were carried out to present the demographic characteristics. Chi-square test, odds ratio with 95% CI was calculated for analyzing differences between study variables using SPSS version-16. Multivariate analysis of lifestyle and dietary predictors of IBS was carried out by the enter method.
結果:
回答率90.5%の181名の学生がアンケートに回答した。約53名（29.28％）がIBSに罹患しており、41名（77.35％）が男性であった。参加者の男性の性別、既婚者の有無、生活状況はIBSの発生と有意に関連していた。IBSの有病率は、医学部出身の学生（P = 0.000）、喫煙者（P = 0.003）、睡眠時間が8時間未満の学生（P = 0.042）、炭酸飲料をよく飲む学生（P = 0.003）の方が高いことがわかった。喫煙、運動頻度、コーヒー摂取量、炭酸飲料摂取量は、生活習慣因子と食事因子の多変量解析において、IBSの強い予測因子であった。
Results: With a response rate of 90.5%, 181 students completed the questionnaire. Around 53 (29.28%) were found to be suffering from IBS with 41 (77.35%) being males. Male gender, married status, and living status of participants were significantly associated with the occurrence of IBS. Prevalence of IBS was found to be more in students who were from the medical college (P = 0.000), students who smoke (P = 0.003), who slept less than 8 h (P = 0.042), and students who often take carbonated drinks (P = 0.003). Smoking, frequency of exercise, coffee intake, and intake of carbonated drinks were strong predictors of IBS on multivariate analysis of lifestyle and dietary factors.
結論:
医学生では過敏性腸症候群の有病率が高いと結論づけた。本研究では、男性の性別、既婚者の有無、ホステルでの生活、喫煙、睡眠時間8時間未満、炭酸飲料はIBSの予測因子であった。医学生を対象に過敏性腸症候群のスクリーニングを行い，介入策を講じることを推奨する．
Conclusion: We conclude that there is an increased prevalence of irritable bowel syndrome among medical students. Male gender, married status, living in hostel, smoking, less than 8 h sleep, and carbonated drinks were predictive factors for IBS in our study. We recommend screening of medical students for irritable bowel syndrome and institution of interventional measures.
