In this cross-sectional study of a representative sample of the US population, environmental exposures to VOCs, especially aromatic compounds, were associated with adverse respiratory effects.

Protein-energy malnutrition is one of the leading causes of childhood morbidity and mortality in developing countries. The purpose of the present study was to measure the prevalence of stunting and its correlates among school children aged 6-12 years in the rural areas of southern Pakistan. We selected 1915 children aged 6-12 years enrolled in 32 primary schools in rural Sindh, Pakistan. Trained community health workers conducted child height and weight measurements and collected information from the parents. The Z-scores for the distribution of height-for-age, weight-for-age, and weight-for-height relative to those of National Center for Health Statistics/Center of Disease Control and prevention (NCHS/CDC) reference population were calculated. Out of 1915 children, 300 (16.5 per cent) were stunted. Female children compared to males were more likely to be stunted (prevalence ratio (PR) = 1.26; 95 per cent confidence interval (CI): 1.02-1.53). Children older than 7 years were more likely to be stunted (PR, 1.40; CI, 1.14-1.72). Fathers who were working as government employees (PR, 1.71; CI, 1.05-2.79), shopkeepers (PR, 2.00; CI, 1.22-3.26) and farmers (PR, 1.43; CI, 0.93-2.22) were more likely to have children who were stunted when compared to landlords. In rural areas of southern Pakistan, sex of child, age of the child, and father's occupation may be considered as important risk factors for stunting among school children aged 6-12 years.

With the rising epidemic of type 2 diabetes worldwide, including the United States, the death and disability due to the suboptimal control of cardiovascular disease associated with this epidemic has made prevention of type 2 diabetes emerge as a primary strategic intervention. Several modalities have been assessed in large randomized controlled trials for diabetes prevention such as lifestyle interventions and various pharmacologic agents. Included in these agents are metformin, thiazolidinediones, acarbose, angiotensin converting enzyme inhibitors, as well as angiotensin receptor blockers. Abrogation of oxidative stress appears to be a common soil hypothesis that explains the favorable effects of these agents on glucose metabolism, including the prevention of diabetes and its complications. This comprehensive review highlights the role of oxidative stress in the pathogenesis of diabetes, with emphasis on the major clinical trials conducted on prevention of type 2 diabetes.

PurposeThe latest mobile technology may shape consumers' motivations by allowing them to order a variety of foods using smartphone apps. Following the stimulus–organism–response (SOR) framework and using a mixed methods approach, this study investigates the impacts of different components of mobile dining on customers' perceived value, which leads to actual purchase intentions. Furthermore, this study examines the moderating effect of the restaurant type.Design/methodology/approachData were collected via an online questionnaire survey from 351 individuals in the city of Jakarta (Indonesia) who actually used mobile apps to order food online. Data analysis was carried out using structural equation modeling.FindingsThe findings reveal that source credibility, review valence, the navigation system, food quality and service quality significantly impact customers' perceived value. Customers' perceived value, in turn, positively affects their purchase intentions. The findings also reveal that the impacts of review valence, the navigation system, food quality and service quality on customers' perceived value depend on the different levels of restaurants.Originality/valueThis study is among the first in the mobile commerce research that studies the impacts of mobile electronic word-of-mouth (eWOM), system quality and overall restaurant image on dining choices by considering actual mobile shoppers. Second, this study extends the SOR model to examine the impact of the mobile environment-based characteristics on the perceived value that leads to purchase intentions. Third, the current study examines whether the relationships that are discussed early on differ based on the restaurant type. The findings of this study could help practitioners achieve a deeper understanding of diners' behaviors due to the perceived benefits of mobile dining.

Latest media technology may shape consumers' new motivations for disseminating word of mouth via mobile social networking sites (SNSs).This research aims to investigate the impact of social media marketing activities in terms of mobile eWOM on different dimensions of online CBBE and behavioral intentions towards online fast causal restaurant industry, using the SO -R consumer response model. Participants (n= 351) resided in Indonesia and had prior experience of mobile application usage. SEM was used to analyze the data. The results indicate that mobile eWOM (stimulus) significantly influenced both consumer emotional, affective and cognitive responses. The emotional affective and cognitive responses significantly influenced behavioral responses. In addition, full mediation effects of CBBE were found between mobile eWOM and consumer response. Study findings emphasize the importance of examining consumer response in terms of mobile eWOM and CBBE. This study offers important theoretical and practical contributions to restaurant operators.

Small-to-medium-sized forest enterprises (SMFEs) offer numerous benefits to rural communities and society as a whole. Less attention has been paid to the sustainability of SMFEs in terms of improving the livelihood of rural communities. This study aims to assess the impact of SMFEs in Khyber-Pakhtunkhwa (KPK), Pakistan, and evaluate their potential role in reducing poverty and promoting rural livelihoods. Primary data were collected from 350 household heads and analyzed using econometric methodologies: The ordinary least squares (OLS) and ordered logit model. Household income, a wealth index, and five capitals of sustainable livelihood have been considered to gauge the impact of SMFEs. The results of the study reveal that there is a strong positive association between SMFEs and improvement in a rural community’s livelihood. The results further showed that households engaged in SMFE-related activities earn 3% more income and possess about 24% more assets. These findings are robust for various dimensions of sustainable livelihood and show positive effects of SMFEs on livelihood assets. This study continues the discussion on several practical implications along with recommendations for future research.

Summaryobjectives To estimate the prevalence of obesity and overweight among adults in a high mountain rural population of Pakistan, and to determine the correlates of excess body weight.design Cross-sectional study. methods A random sample of 4203 adults (aged 18 years and over) was selected by stratified random sampling from 16 villages in north Pakistan. Trained medical students measured height, weight and blood pressure. Trained interviewers obtained information from participants on sociodemographic variables, use of snuff, daily cigarette consumption, hypertension and family history of hypertension. Body mass index (BMI) calculated as kg/m 2 was used to define overweight (BMI ‡ 25 kg/m 2 ) and obesity (BMI ‡ 30 kg/m 2 ).results Using weight and height data available for 1391 men and 2754 women, mean BMI was 22.4 (95% CI 21.9, 22.9) for men and 22.6 (95% CI 21.9, 23.2) for women. The age-adjusted prevalence of BMI ‡ 25 (overweight/obesity) was 13.5% for men and 14.1% for women. Overweight/obesity increased with age and the increase per year was identical for both men and women [adjusted odds ratio (AOR) ¼ 1.01, 95% CI 1.01, 1.03]. Overweight/obese men and women were more likely to be hypertensive (men, AOR ¼ 3.32, 95% CI 2.16, 5.09; women, AOR ¼ 1.70, 95% CI 1.21, 2.39). Overweight/obese women were more likely to work in business or as skilled workers (AOR ¼ 6.24, 95% CI 1.18, 32.83) while overweight/obese men were more likely to work as government employees (AOR ¼ 2.59, 95% CI 1.66, 4.03). Family history of hypertension was a significant correlate of overweight/obesity in men (P value 0.004) and women (P value 0.000). Overweight/obese men and women were less likely to use smokeless tobacco (men, AOR ¼ 0.65, 95% CI 0.43, 0.97; women, AOR ¼ 0.54, 95% CI 0.35, 0.85).conclusion The prevalence of risk factors for non-communicable diseases (NCDs) in Pakistan is expected to increase as further epidemiologic, nutritional and demographic changes occur. The assessment of excess body weight, and patterns and determinants of other risk factors for NCDs is important to provide useful guidelines in the planning of interventions to counter a growing problem.
