Associations between Academic Stressors, Reaction to Stress, Coping Strategies and Musculoskeletal Disorders among College Students

Background: The adverse health effects of stress are enormous, and vary among people, probably because of differences in how stress is appraised and the strategies individuals use to cope with it. This study assessed the association between academic stress and musculoskeletal disorders  (MSDs) among 1365 undergraduates.Methods: This was a cross-sectional study conducted in a Nigerian university at the beginning of the 2010/2011 academic session with the same group of participants. The Life Stress Assessment Inventory, Coping Strategies Questionnaire, and Short Musculoskeletal Function Assessment were administered as tools of data gathering.Results: Students’ stress level and associated MSDs were higher during the examination period than the pre-examination periods. Stressors were significantly associated with increased risk of MSDs in both sexes were those related to changes (odds ratio (OR) = 1.7, p = 0.002) and pressures (OR = 2.09, p = 0.001). Emotional and physiological reactions to stress were significantly associated with MSDs in both sexes, with higher odds for MSDs in females, whereas cognitive and behavioral reactions showed higher odds (though non-significant) in males. The risk of MSDs was higher in respondents who adopted avoidance and religious coping strategies compared with those who adopted active practical and distracting coping strategies.Conclusions: Stress among students could be significantly associated with MSDs depending on individuals’ demographics, stressors, reactions to stress, and coping methods. Interventions to reduce stress-induced MSDs among students should consider these factors among others.Keywords: Academic stressors, Coping strategies, Musculoskeletal disorder

Changes in Serum Markers of Atherogenesis and Hematological Profile after the consumption of Quail eggs

Previous studies suggest that diets with more eggs than is recommended may be used as part of a healthy diet in some countries. However, whether quail egg diets could form part of such diet has not been explored. The aim of the present study is to evaluate the effect of quail egg consumption on serum markers of atherogenesis and hematological parameters in healthy volunteers. Thirty adult subjects participated in this study after ascertaining their baseline health status. They were fed 3 eggs per day and 8hourlyfor 30 days. They were evaluated for serum levels of cholesterol sub-fractions, AIP and hematological parameters at days 0, 10 and 30 after the consumption of quail eggs. At day10, serum levels of cholesterol sub-fractions (TG, HDL-C and LDL-C) were not significantly (p>0.05) different from the corresponding values at baseline. Serum levels of VLDL-C and calculated AIP significantly (p<0.05) decreased compared to the levels at baseline. At day 30, serum levels of HDL-C, TG and VLDL-C significantly (p<0.05) increased, while LDL-C and AIP significantly decreased. Also, total RBC, HB, PCV, MCV, MCH and MCHC were not significantly different from the levels at baseline. At day 30, RBC, PCV and HB significantly (p<0.05) increased compared to the levels at baseline, while MCV, MCH and MCHC were not significantly (p>0.05) different from the baseline values. Indeed, long-term consumption of quail egg may be associated with improvement in serum markers of atherogenesis and hematological parameters due to its varied nutrient constituents and their activities

Prevalence and risk factors for diabetes and diabetic retinopathy: results from the Nigeria national blindness and visual impairment survey.

BACKGROUND: In Nigeria, urbanisation and increasing life expectancy are likely to increase the incidence of non-communicable diseases. As the epidemic of diabetes matures, visual loss from diabetic retinopathy (DR) will increase unless mechanisms for early detection and treatment improve, and health systems respond to the growing burden of non-communicable diseases. METHODS: A nationally-representative population-based sample of 13,591 participants aged ≥40 years selected by multistage-stratified-cluster-random-sampling with probability-proportional-to-size procedures were examined in 305 clusters in Nigeria between January 2005 to June 2007. All were asked about history of diabetes and underwent basic eye examination. Visual acuity (VA) was measured using logMAR E-chart. Participants with VA11.1mmol/l or had DR. Data in the subsample were used to estimate the prevalence and to analyse risk factors for diabetes and DR using multivariable logistic regression. Additional information on the types of DR was obtained from participants not in the subsample. RESULTS: In the subsample, 164 participants were excluded due to missing data; and 1,595 analysed. 52/1,595 had diabetes, a prevalence of 3.3% (95%CI 2.5-4.3%); and 25/52(48%) did not know. Media opacity in 8/52 precluded retinal examination. 9/44(20.5%) had DR. Higher prevalence of diabetes was associated with urban residence (Odds ratio [OR]1.87) and overweight/obesity (OR3.02/4.43 respectively). Although not statistically significant, DR was associated with hypertension (OR3.49) and RBG>15.0mmol/L (OR8.10). Persons with diabetes had 3 times greater odds of blindness. Of 11,832 other participants in the study sample, 175(1.5%) had history of diabetes; 28 had DR. Types of DR (total=37) included 10.8% proliferative, 51.4% macular oedema. CONCLUSION: The age-adjusted prevalence of diabetes in Nigeria was 3.25% (95%CI 2.50-4.30) and over 10% of people with diabetes aged ≥40 years had sight-threatening-DR. These data will enable the development of better public health strategies for the control of diabetes and planning services for DR to prevent vision loss
