Adolescent pregnant women's perception of health practices: A qualitative study.

AIM: To explore adolescent pregnant women's perception of health practices. DESIGN: A qualitative study. METHOD: Fifteen pregnant women in Tehran (capital of Iran) were selected based on purposive sampling to participate in semi-structured, in-depth interviews. The content of interviews was recorded and transcribed and then analysed using conventional content analysis. RESULTS: The first theme extracted was health practice with main categories of balanced rest/activity pattern, observance of an appropriate diet, sensitivity to personal health, observance of an appropriate pattern of social interactions, religious and spiritual orientations, recreational and leisure time activities, and stress management; second theme was perceived benefits with main categories of a sense of physical health improvement, a sense of mental health improvement, positive attitudes towards the effect of nutrition on pregnancy and childbirth health; and third theme was effective factors with main categories of facilitators of health practices and inhibitors of health practices. CONCLUSIONS: Most pregnant adolescents' perception of health practices is at a satisfactory level; however, some inhibitors of health practice were explored in this study. These should be improved by adopting appropriate approaches in health policies. No Patient or Public Contribution.

The effect of vitamin D on sleep quality: A systematic review and meta-analysis.

Background: Poor sleep quality is a common problem in the general population that affects the quality of life of individuals. Aim: This systematic review aimed to determine the effect of vitamin D on sleep quality (primary outcome) and side effects (secondary outcome). Methods: A systematic search was performed using Cochrane Library, PubMed, Embase, Web of Sciences, Scopus, Google Scholar, SID, and Magiran databases with no limit at the time of publication. Cochrane collaboration instrument was used to evaluate the quality of the included studies. RevMan software was used for meta-analysis. Mean Difference was calculated due to the same sleep quality measurement tools in all studies. Heterogeneity of studies was assessed using I-squared (I2). Due to high heterogeneity (I2 > 75%), Random Effect was used instead of Fixed Effect. Results: Out of a total of 1637 titles and abstracts found, after removing duplicate items (23 items), 1596 items were removed due to irrelevance and lack of inclusion criteria. 18 articles were fully studied due to insufficient abstract information and finally, 5 articles were entered into systematic review and meta-analysis. The results of the meta-analysis showed that the use of vitamin D supplementation significantly improves sleep quality (MD: -1.32; 95%CI: -2.55 to -0.09; P = 0.04). Conclusions: Also, according to the findings of this study, receiving vitamin D supplementation did not cause any side effects. According to the results of this review study, sleep quality in people receiving vitamin D significantly improved compared to the control group.

Comparison of fear, anxiety and self-efficacy of childbirth among primiparous and multiparous women.

BACKGROUND: The aim of this study was to compare fear of childbirth, state and trait anxiety, and childbirth self-efficacy among primiparous and multiparous women in Ahvaz, southwest of Iran. METHODS: This cross-sectional study was conducted with 200 pregnant women (100 primiparous and 100 multiparous women) who had been admitted to the maternity ward of hospitals affiliated to Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran. The instruments used for data collection in this study included a demographic questionnaire, Delivery Fear Scale (DFS), Spielberger's State-Trait Anxiety Inventory (STAI), and Childbirth Self-Efficacy Inventory (CBSEI). The data were analyzed by chi-square test and independent t-test. Also, the univariate general linear model was used by adjusting for the socio-demographic and obstetric characteristics that were considered as possible confounding variables. RESULTS: The mean score of DFS in primiparous women was significantly higher than that of multiparous women. The mean of the overall score of childbirth self-efficacy of primiparous women was significantly lower than that of multiparous women. The mean score of the outcome expectancies and self-efficacy expectancies was significantly lower in primiparous women compared with multiparous women. There was no statistically significant difference between the two groups in terms of the mean score of STAI. After adjusting for possible confounding variables, the differences between the two groups in terms of fear of childbirth scores, overall childbirth self-efficacy score and self-efficacy expectancies remained significant. CONCLUSION: Given the high fear of childbirth and low childbirth self-efficacy in primiparous women compared to the multiparous women, appropriate interventions should be adopted by health care providers in order to reduce fear and improve childbirth self-efficacy in primiparous women.

Effect of Education on Preventive Behaviors of Osteoporosis in Adolescents: A Systematic Review and Meta-Analysis.

BACKGROUND: Osteoporosis is one of the diseases that can be prevented by correcting health behaviors during adolescence. OBJECTIVE: This study was conducted to evaluate the effect of education on preventive behaviors of osteoporosis including physical activity, calcium intake and practice (primary outcomes) and knowledge and attitude related to osteoporosis (secondary outcomes) in adolescents. METHOD: A search was done in Cochrane Library, PubMed, Embase, Web of Sciences, Scopus, Google Scholar, SID and Magiran regardless of the time limit. To evaluate the quality of selected controlled trials, Cochrane collaboration' instrument was used for assessing the risk of bias. RevMan software was used to analysis and report the data. RESULTS: Of 2159 articles retrieved, 20 of them were reviewed and 18 of them entered the mete-analysis. The meta-analysis showed significant differences between the education and control groups in terms of calcium intake (SMD = 0.78, 95%CI = 0.55 to 1.02, P < 0.00001), practice (SMD = 0.54, 95%CI = 0.41 to 0.68, P < 0.0001), knowledge (SMD = 1.76, 95%CI = 1.10 to 2.42, P < 0.00001) and attitude (SMD = 0.96, 95%CI = 0.53 to 1.40, P < 0.0001) mean score in adolescents but education is not effective on average minute/week of physical activity per week (MD = 31.94, 95%CI = -6.53 to 70.40, P = 0.10), mean score of physical activity (MD = 2.66, 95%CI = -0.55 to 5.88, P = 0.10) and percent of students participated in the physical activity (OR = 1.45, 95%CI = 0.30 to 6.91, P = 0.64). CONCLUSION: Education is effective in improving their knowledge and attitudes toward osteoporosis. It can also improve some health-related behaviors for bone health such as sufficient dairy calcium intake but it has not been effective in establishing a regular exercise program.
