Abstract

Research on ergonomic risk factors for neck pain among Islamic boarding school students remains scarce, despite their prolonged study and Qur’an memorization activities in static sitting postures. Non-neutral body posture during learning may increase the risk of musculoskeletal disorders (MSDs), particularly neck pain, which can impair concentration and quality of life. This analytic cross-sectional study aimed to assess students’ body posture during study and memorization activities and to examine its association with neck pain. A total of 72 boarding and non-boarding students participated. Data were collected using questionnaires and the Rapid Upper Limb Assessment (RULA), and analyzed with chi-square tests and logistic regression to obtain prevalence ratios (PR) and p-values. Neck pain was reported by 63.9% of respondents; 72.2% exhibited poor sitting posture, and 80.6% reported moderate-to-severe stress. Bivariate analysis showed a significant association between stress level and neck pain (p = 0.033; PR = 2.19; 95% CI: 1.25–3.83). In multivariate logistic regression, no variable reached conventional statistical significance; however, students with moderate-to-severe stress had a 3.81-fold higher risk of neck pain (p = 0.057). These findings underscore the need for integrated ergonomic and psychosocial interventions in Islamic boarding school settings to reduce neck pain risk among students.

Abstract

Obesity is one of the risk factors for atherosclerosis, and its occurrence and development are associated with fat accumulation and adipocyte differentiation. Thus, the suppression of adipocyte differentiation can be a potential anti-obesity approach. This study examined the effect of mangosteen pericarp extract (MPE) and xanthones (α-Mangostin (AM) and γ-Mangostin (GM)) on the expression of PPARγ, C/EBPα, SCD1, LPL, aP2, adipoQ, and FAS in 3T3-L1 cells. Concentrations of MPE and xanthones used were based on cytotoxicity assays on 3T3-L1 cells. Three different MPE concentrations (0, 25, and 50 µg/mL), three AM concentrations (0, 25, and 50 µM), and GM concentrations (0, 50, and 75 µM) were used. The expressions of PPARγ, C/EBPα, SCD1, LPL, aP2, adipoQ, and FAS genes were measured using real-time quantitative PCR. Gene expression was downregulated in cells treated with 50 µg/mL MPE and 50 µM GM. However, 25 µM and 50 µM AM did not suppress PPARγ and SCD1 expression. The 50 µM AM treatment also failed to reduce aP2 gene expression. Overall, MPE and GM demonstrated potential anti-adipogenesis and anti-obesity effects by suppressing the expression of PPARγ, C/EBPα, SCD1, LPL, aP2, adipoQ, and FAS in 3T3-L1 cells.
