Exploring the relationship of sleep quality with drug use and substance abuse among university students: a cross-cultural study

Lifestyle factors associated with poor sleep quality among undergraduate dental students at a Malaysian private university

OBJECTIVE

The purpose of this study was to look into the associations between lifestyle factors, gender, clinical level, and sleep quality among undergraduate dental students at a private university in Malaysia.

MATERIAL AND METHODS

A self-administered Pittsburg sleep quality index (PSQI) scale and the lifestyle and habits questionnaire-brief (LHQ-B) were used in this cross-sectional study. A global PSQI score of greater than 5 indicates poor sleep quality. All university dental students were invited to take part. Descriptive statistics and logistic regression analyses were used to analyze the data.

RESULTS

A total of 338 students took part in the study, with a response rate of 90.4%. The proportion of females was higher (68.3 %) and more than half of the respondents (56.7 %) were in their clinical years. The prevalence of poor sleep quality was 36.7%. At multivariable level, poor sleep quality was associated with being male (OR=1.72 [95% confidence interval (1.05, 2.83)] and engaging in an unhealthy lifestyle for psychological health (OR=2.64 [95% confidence interval (1.34, 5.21)] and nutrition (OR=2.48 [95% confidence interval (1.028, 4.82)].

CONCLUSION

The prevalence of poor sleep quality among undergraduate dental students in our study was comparable to that found in other studies. Male students were more likely to have poor sleep quality than female students. Our findings indicate that poor sleep quality (PSQI score >5) may be linked to unhealthy lifestyle habits related to psychological health and nutrition. Health education that emphasizes these domains is essential for improving their lifestyle habits and sleep quality.

Sleep Quality Among Adolescents and Its Relation to Inhalant, Khat, and Internet Use, and Physical Illness: A Community-Based Exploratory Cross-Sectional Study

Sleep-related health problems are under investigated among adolescents in low-income countries, including our country, Ethiopia. Therefore, this study aimed to assess the sleep quality and its associated factors among adolescents aged 10 to 19 years in Ethiopia. A community-based cross-sectional study was conducted among 799 adolescents from May 27 to July 27, 2021, using a systematic random sampling technique. Sleep quality was assessed by using the Petersburg sleep quality index. The data was entered into Epi-data version 3.1 and exported to the Statistical Package for Social Science (SPSS) Version 21. A logistic regression model was used, and variables with a P-value less than .05 in the final fitting model were stated as independent predictors of poor sleep quality (PSQ). About 1 in 3 adolescents (38%) had a poor sleep quality. The rates of inhalant, khat, and internet use disorders were 16%, 38%, and 18%, respectively. Also, 27.4% of adolescents used alcohol as a sleep medication, and 75% of adolescents with internet addiction had PSQ. Moreover, adolescents with physical illness had about 4 times higher odds of association with PSQ (AOR = 3.76 and 95% CI = 2.30-6.15%CI), and inhalant use disorder (AOR = 1.98 and 95% CI = 1.29-3.04%CI), internet addiction (AOR = 3.33 and 95% CI = 2.09-5.30%CI), and khat use disorder (AOR = 1.74 and 95% CI = 1.11-2.73%CI), were positively associated with PSQ. PSQ was higher among adolescents, and problematic inhalants, khat, and internet use and physical illness were risk factors for PSQ.
