Body mass index and health related quality of life in elementary school children: a pilot study

<p>Abstract</p> <p>Background</p> <p>We investigated the relationship between Body Mass Index (BMI) and health-related quality of life (HRQOL) indicated by baseline health status in elementary school children.</p> <p>Methods</p> <p>Data were obtained via parents whose children enrolled in an elementary school, kindergarten to fourth grade, in southern Mississippi in spring 2004. Parents completed the <it>SF-10 for Children™</it>, a brief 10-item questionnaire designed to measure children's HRQOL on a voluntary basis.</p> <p>Results</p> <p>A total of 279 parents completed the questionnaires for their children. On average, physical and psychosocial summary scores, major indicators for HRQOL, were significantly higher among the elementary school children in our study relative to those from U.S. children overall (p < 0.0001 and p = 0.0007, respectively). Males tended to have better physical functioning than their female classmates, whereas females had better psychosocial health. Overall, except for third graders, the physical summary scores increased as grade level increased. The means for psychosocial score fluctuated without a clear pattern over the five grade levels. High level of BMI was significantly associated with children's physical summary scores below 50, a norm used for U.S. children (p = 0.003). Gender and grade were not significant predictors of children's physical and psychosocial scores.</p> <p>Discussion</p> <p>This study can be used as baseline information to track changes over time, in BMI and health status among the elementary school children. In addition, this study can be used to investigate relationships between BMI, health status, intellectual ability, and performance in school.</p> <p>Conclusion</p> <p>The findings suggest that programs designed to encourage children to lose weight in a healthy manner, thus reducing their BMI, could improve the physical and psychosocial health, and subsequently increase HRQOL.</p

Sexual attitudes, pattern of communication, and sexual behavior among unmarried out-of-school youth in China

<p>Abstract</p> <p>Background</p> <p>In recent years, more adolescents are engaging in premarital sex in China. However, only a limited number of studies have explored out-of-school youth's sexual attitudes and behaviors, critical for prevention intervention development.</p> <p>Methods</p> <p>Using data from the baseline survey of a comprehensive sex education program that was conducted in a suburb of Shanghai in 2000–2002, this study describes sexual attitudes, patterns of communication on sexual matters, and premarital sexual behavior among 1,304 out-of-school youth. Multivariate logistic regression analysis was conducted to examine the factors associated with youth's premarital sexual intercourse.</p> <p>Results</p> <p>The majority (60%) of out-of-school youth held favorable attitudes towards premarital sex. Males were more likely to have favorable attitudes compared with females. Male youth generally did not communicate with either parent about sex, while one-third of female youth talked to their mothers about sexual matters. Both males and females chose their friends as the person with whom they were most likely to talk about sexual matters. About 18% of the youth reported having engaged in sexual intercourse. One-fifth of sexually active youth had always used a contraceptive method, and one-quarter had been pregnant (or had impregnated a partner). There were no gender differences in rate of premarital sex or frequency of contraceptive use. Multivariate analysis revealed that age, education, family structure, parent's discipline, attitudes towards premarital sex, pattern of communication and dating were significantly associated with youth premarital sex.</p> <p>Conclusion</p> <p>A substantial proportion of out-of-school youth engage in risky sexual behaviors. Prevention programs that empower communication and sexual negotiation skills, and promote condom use should be implemented for this vulnerable group.</p

Understanding the Dynamics of Condom Use Among Female Sex Workers in China

Objectives and Background: Condom use within the context of commercial sex work is a complex issue. Drawing on a hypothesized theoretical model that combines concepts from the health belief model and social cognitive theory, this study examines the complex relationships between multiple levels of determinant factors of condom use with clients among female sex workers in China. Methods: Data were collected through the baseline Survey of an HIV prevention project among 454 establishment-based female sex workers in a rural county of Guangxi, China in 2004. Path analysis was performed to test the hypothesized model that specifies relationships between all observed variables. Results: Within the context of this study\u27s model, STD/HIV knowledge and condom use skills were related to self-efficacy which in turn related to condom use. Susceptibility/severity was related to perceived benefits of unprotected sex. Perceived benefits were in turn inversely related to condom use. STD/HIV knowledge, condom use skills, and susceptibility/severity had no direct effect on condom use. Their effects on condom use were mediated by self-efficacy and perceived benefits. Self-efficacy was not associated with perceived benefits of unprotected sex. Perceived establishment-level support was positively related to condom use. Conclusions: Self-efficacy, perceived benefits of unprotected sex, and perceived establishment-level support are proximate determinants of condom use among female sex workers. Future HIV prevention interventions should integrate these factors into conceptual frameworks

Effects of neurofeedback on the short-term memory and continuous attention of patients with moderate traumatic brain injury: A preliminary randomized controlled clinical trial.

PurposeThere are some studies which showed neurofeedback therapy (NFT) can be effective in clients with traumatic brain injury (TBI) history. However, randomized controlled clinical trials are still needed for evaluation of this treatment as a standard option. This preliminary study was aimed to evaluate the effect of NFT on continuous attention (CA) and short-term memory (STM) of clients with moderate TBI using a randomized controlled clinical trial (RCT).MethodsIn this preliminary RCT, seventeen eligible patients with moderate TBI were randomly allocated in two intervention and control groups. All the patients were evaluated for CA and STM using the visual continuous attention test and Wechsler memory scale-4th edition (WMS-IV) test, respectively, both at the time of inclusion to the project and four weeks later. The intervention group participated in 20 sessions of NFT through the first four weeks. Conversely, the control group participated in the same NF sessions from the fifth week to eighth week of the project.ResultsEight subjects in the intervention group and five subjects in the control group completed the study. The mean and standard deviation of participants' age were (26.75&nbsp;±&nbsp;15.16) years and (27.60&nbsp;±&nbsp;8.17) years in experiment and control groups, respectively. All of the subjects were male. No significant improvement was observed in any variables of the visual continuous attention test and WMS-IV test between two groups (p&nbsp;≥&nbsp;0.05).ConclusionBased on our literature review, it seems that our study is the only study performed on the effect of NFT on TBI patients with control group. NFT has no effect on CA and STM in patients with moderate TBI. More RCTs with large sample sizes, more sessions of treatment, longer time of follow-up and different protocols are recommended
