Recent research underscores the need for increasing use of genetic testing for cancer risk in Latinos. This study examined the influence of acculturation on attitudes, beliefs about and familiarity with genetic testing for cancer risk in a community-based sample of Latinas in East Harlem, New York City (N = 103). Multivariate linear regression models analyzed the relationship of acculturation to: (1) familiarity (2) perceived benefits (3) perceived barriers and (4) concerns about abuses of genetic testing for cancer risk. Controlling for sociodemographic factors, results revealed that with increasing acculturation Latinas were more familiar with genetic testing (β = 1.62, SE = 0.72, p = 0.03), more likely to cite perceived benefits (β = 1.67, SE = 0.79, p = 0.04), and less likely to report perceived barriers related to genetic testing (β = −2.76, SE = 1.64, p = 0.10). Study results may help inform the development of culturally-appropriate health education outreach materials and programs targeted to increase awareness, knowledge and understanding about genetic testing for cancer risk within Latinas.  相似文献

为探讨阅读动机和阅读活动在家庭社会经济地位与阅读成就关系之间的中介机制,采用问卷法对我国东部某省3所学校468名7~9年级学生进行调查,使用结构方程建模的方法对中介模型进行检验。结果表明:家庭社会经济地位、阅读动机、阅读活动及阅读成就之间呈显著正相关;家庭社会经济地位对阅读成就的直接效应不显著,但可以通过阅读动机和阅读活动的链式中介作用对阅读成就产生间接的影响。  相似文献

With interest in body image and body change behaviors growing around the world, there has been surprisingly little research conducted in Latin America on these issues. In order to gain some understanding of them in this context, this study investigated body image and body change behaviors, and the sociocultural factors that may influence them, among 337 Chilean adolescents aged 12–18 years. Participants completed a questionnaire that assessed BMI, body dissatisfaction, strategies to lose weight and strategies to increase muscle bulk. In addition, perceived pressure from family, peers, and the media to change body shape was evaluated. Results were partially consistent with those reported in Western nations. Girls were found to report greater body dissatisfaction than boys, but no difference was found between males and females in perceived pressure from adults in the family or from older siblings/cousins to lose weight. However, girls experienced higher levels of perceived pressure to lose weight from the media than boys, and boys reported greater perceived pressure from peers to lose weight than girls, and more pressure than girls from all sources to increase muscle bulk. These findings are discussed in relation to research conducted in other contexts, and it is concluded that findings from other locations may not be applied universally.  相似文献

There is increasing evidence that children display high levels of weight and muscle concerns, which include body dissatisfaction and problem eating. In order to address these issues, researchers have designed and implemented prevention programs for this age group. Thirteen published studies were located and reviewed, with children aged 8-12 years from elementary schools, or equivalent. Overall, the programs were shown to be effective in improving children's knowledge at post-test and at follow-up assessments. However, there is limited evidence to show that the programs reduced or prevented body image concerns and/or problem eating. Too few studies have examined muscle concerns so no conclusions can yet be drawn about this domain. Limitations of the studies and suggestions for future prevention efforts are discussed.  相似文献

This study examined the role of positive and negative appearance-based comments on body dissatisfaction and drive for muscularity among young adult males. The direct and moderating effect of self-esteem were also investigated; and BMI, age, and social desirability were included as covariates. The participants were 214 males aged between 18 and 30 years. More frequent negative comments were associated with higher body dissatisfaction whilst more frequent positive comments were associated with lower body dissatisfaction. However, both frequent negative and positive commentary were associated with higher drive for muscularity. Self-esteem was also associated with both body dissatisfaction and the drive for muscularity, but it did not moderate that influence of either positive or negative messages. Longitudinal research is now needed to determine the directionality of these relationships. Further research is required to establish the contexts in which positive and negative messages are associated with body dissatisfaction and the drive for muscularity.  相似文献

A home‐based intervention designed for impoverished Latino families of low‐birth‐weight infants was implemented, and the efficacy assessed for infants and mothers. Specially trained public health nurses visited the participants' homes for 4 months for the “short” and 12 months for the “extended” intervention groups. Mothers received support and training in infant care. A third group did not receive the intervention. Assessments were at 4‐ to 6‐month intervals from 1 to 24 months. Although the extended visitation group showed no benefits from the intervention, the short visitation group had higher scores on maternal confidence at one month, and on the Bayley Mental Scores at four months than the group receiving no intervention and extended intervention. The nonvisitation group scored significantly higher than both intervention groups on the HOME scores and on the Mother–Infant Interaction and Feeding scores at three different assessment periods. These data suggest that for poor Latino families home intervention is not beneficial across the board. Instead, efforts should be made to identify families that could benefit from intervention and to tailor the program to the specific needs of Latino families. © 2000 Michigan Association for Infant Mental Health.  相似文献
