Abstract
This study aimed to explore racial/ethnic differences in the attitudes toward Alzheimer's Disease (AD) and dementia caregiving among midlife women who were family caregivers of persons living with AD (MWPLAD) in the U.S. and examine the associations of the attitudes to their health outcomes. This was a cross-sectional online survey study among 172 MWPLAD. The instruments included: the Attitude toward AD and Related Dementias Scale, the Questions on Attitudes toward AD Caregiving, the Social Readjustment Rating Scale, the EQ-5D-5L and the Midlife Women's Symptom Index. Multiple linear regression analyses were conducted. There were significant racial/ethnic differences in caregivers' attitudes toward dementia caregiving, health-related quality of life, and total severity scores of symptoms (p < .01). Controlling for covariates including race/ethnicity, caregivers' positive attitudes toward dementia caregiving were significantly associated with their health outcomes (p ≤ .05). Interventions for MWPLAD need to consider racial/ethnical differences in their attitudes toward dementia caregiving.

Abstract
Diabetes management at school demands close collaboration of multiple stakeholders, including students with diabetes and parents, school nurses, teachers/staff, and local health care providers. This scoping review identified and synthesized evidence concerning factors that contributed to the quality and effectiveness of diabetes care implementation in U.S. K-12 schools. Forty-six studies met the eligibility criteria and were included. Five common factors emerged surrounding training and experiences, communications, parent engagement, resource allocations, and school environment. Complex interactions between multiple stakeholders jointly determined the quality of school diabetes care. A conceptual model was established to elucidate the complex interactions between multiple stakeholders and the relevant facilitators and barriers. Future research should improve sample representativeness, contrast school diabetes care practices to the national guidelines, and assess the impact of the social, economic, and political environment at federal, state, local/district levels on school diabetes care implementation.

Abstract
OBJECTIVE One of the most prevalent and distressing symptoms after breast cancer treatment is menopausal symptoms. Asian American breast cancer survivors have lower quality of life and often receive inadequate management of menopausal symptoms compared to other racial/ethnic groups. Technology-based programs could be a solution to fill the gap in care. The purpose of this study was to test the efficacy of a technology-based information and coaching/support program on menopausal symptoms of Asian American breast cancer survivors. METHODS This study adopted a randomized pretest/post-test group design among 91 Asian American breast cancer survivors (42 in an intervention group who used the program and the American Cancer Society Web site and 49 in a control group who used only the American Cancer Society Web site). The intervention was a theory-driven and culturally tailored intervention program that aimed to provide information and coaching/support using computers and mobile devices. Multiple instruments were used to measure background characteristics and menopausal symptoms at pretest, post 1-month, and post 3 months. An intent-to-treat linear mixed-model growth curve analysis was used to analyze the data. RESULTS The intervention group showed a significant decrease in the distress scores of menopausal symptoms over time: physical (β = -0.07, P = 0.08), psychological (β = -0.13, P = 0.05), psychosomatic (β = -0.17, P = 0.06), and total symptoms (β = -0.19, P = 0.01). Theory-based variables including attitudes, social influences, and self-efficacy partially mediated the impact of the intervention on the distress scores of menopausal symptoms (P < 0.10). CONCLUSIONS The program was effective in alleviating menopausal symptoms of Asian American breast cancer survivors.

Abstract
OBJECTIVE To determine the efficacy of a 4-month school-based health, nutrition and exercise intervention on body fatness and examine possible effects of demographic and anthropometric covariates. METHODS Height, weight, waist circumference and body composition were measured in a diverse population of 644 NYC middle school students (mean ± SD age 12.7 ± 0.9 years; 46% male; 38% Hispanic, 17% East Asian, 15% South Asian, 13.5% African American, 8.5% Caucasian, 8% other) during the fall and spring semesters. Year 1 participants (n = 322) were controls. Experimental participants (year 2, n = 469) received a 12-session classroom-based health and nutrition educational programme with an optional exercise intervention. RESULTS Groups were demographically and anthropometrically similar. The intervention resulted in significant reductions in indices of adiposity (ΔBMI z-scores [-0.035 ± 0.014; p = 0.01], Δ% body fat [-0.5 ± 0.2; p < 0.0001] and Δwaist circumference [-0.73 ± 0.30 cm; p < 0.0001]). Intervention effects were greater (p = 0.01) in men (ΔBMI z-score = -0.052 ± 0.015) versus women (0.022 ± 0.018), participants who were obese (ΔBMI z-score -0.083 ± 0.022 kg m-2) versus lean (-0.0097 ± 0.020 kg m-2) and South Asians (Δ% body fat -1.03 ± 0.35) versus total (-0.49 ± 0.20%) participants (p = 0.005). CONCLUSION A 4-month school-based health intervention was effective in decreasing measures of adiposity in middle school students, particularly in men, participants who were obese and South Asians.

Abstract
OBJECTIVE Based on previous studies, a Web-based physical activity promotion program with educational modules on menopausal symptoms and physical activity has been developed for Asian American midlife women to reduce their menopausal symptoms through increasing their physical activity. The purpose of this pilot randomized intervention study was to determine the efficacy of the Web-based program in improving menopausal symptom experience of Asian American midlife women. METHODS This was a randomized repeated measures pretest/posttest (pretest, post 1 month, and post 3 months) control group study among 29 Asian American midlife women. Multiple instruments were used, including the Midlife Women's Symptom Index and the Kaiser Physical Activity Survey. The data were analyzed using a mixed-model growth curve analysis. RESULTS Over time, total severity scores decreased for the control group (-0.53, P < 0.10), whereas they did not exhibit a meaningful change for the intervention group. Both study groups experienced improvement in active living habits over time, but such an improvement was greater for the intervention group (β = 0.29, P < 0.001) than for the control group (β = 0.08, P < 0.10). The time × group interactions for total severity scores were not statistically significant anymore after controlling for physical activity (-0.34 for the control group, P = 0.10). CONCLUSIONS The findings supported the feasibility of a 3-month Web-based intervention for menopausal symptom management among Asian American midlife women and the preliminary efficacy of the program in increasing their physical activity.

Abstract
Type 1 diabetes is one of the most common chronic childhood diseases, while type 2 diabetes in children is increasing at alarming rates globally. Against this backdrop, the school is a critical environment for children with diabetes. They continue to face barriers to education that may lead to depression, poor academic performance, and poor quality of life. To address these challenges, diabetes interventions have been implemented in school and the goal was to systematically review these interventions and their outcomes between 2000 and 2013. Fifteen studies were included in the narrative synthesis. Education of school personnel was the main focus before 2006. Studies reported gains in knowledge and perceived confidence of school staff. Since 2006, more comprehensive interventions have been developed to promote better care coordination and create a safe school environment. These studies reported improved diabetes management and quality of life of students. Assessment tools varied and study design included randomized controlled trials, quantitative and qualitative methods. Although many of the studies reported a significant difference in the parameters measured, it was not possible to determine optimal ways to improve the health, quality of life and academic performance of children with diabetes, given the disparity in scope, assessment tools and measured outcomes. Experimental designs, longer follow-up studies, larger sample sizes, and a higher number of participating schools are critical issues to consider in future studies. Most of the research was conducted in North America and further research is needed in other parts of the world. Significance for public health Diabetes is one of the most common chronic childhood diseases; both type 1 and type 2 diabetes are increasing in children globally. Against this backdrop, the school is a critical environment for children with diabetes. This systematic literature review on school-based diabetes interventions and their outcomes demonstrates that increasing efforts are being made to improve diabetes care and create a safe school environment. Studies reported gains in knowledge and confidence of school staff, as well as improved health and quality of life of students. Given the disparity of the assessment tools used, it was not possible to determine optimal ways to improve the health, quality of life and academic performance of children with diabetes. Future evaluations should include experimental designs, longer follow-up studies, and larger sample sizes. School-based diabetes interventions and solid evaluations will contribute to improving diabetes school policies and ensuring children with diabetes have the same educational opportunities as other children.

Abstract
CONTEXT Systematic reviews of public health interventions are useful for identifying effective strategies for informing policy and practice. The goals of this review were to (1) update a previous systematic review of physical activity interventions in Latin America which found that only school-based physical education had sufficient evidence to recommend widespread adoption; (2) assess the reporting of external validity elements; and (3) develop and apply an evidence typology for classifying interventions. EVIDENCE ACQUISITION In 2010-2011, community-level, physical activity intervention studies from Latin America were identified, categorized, and screened based on the peer-reviewed literature or Brazilian theses published between 2006 and 2010. Articles meeting inclusion criteria were evaluated using U.S. Community Guide methods. External validity reporting was assessed among a subset of articles reviewed to date. An evidence rating typology was developed and applied to classify interventions along a continuum based on evidence about their effectiveness in the U.S. context, reach, adoption, implementation, institutionalization, and benefits and costs. EVIDENCE SYNTHESIS Thirteen articles published between 2006 and 2010 met inclusion criteria and were abstracted systematically, yet when combined with evidence from articles from the previous systematic review, no additional interventions could be recommended for practice. Moreover, the reporting of external validity elements was low among a subset of 19 studies published to date (median=21% of elements reported). By applying the expanded evidence rating typology, one intervention was classified as evidence-based, seven as promising, and one as emerging. CONCLUSIONS Several physical activity interventions have been identified as promising for future research and implementation in Latin America. Enhanced reporting of external validity elements will inform the translation of research into practice.

Abstract
BACKGROUND The World Health Organization (WHO) estimates that 1.9 million deaths worldwide are attributable to physical inactivity and at least 2.6 million deaths are a result of being overweight or obese. In addition, WHO estimates that physical inactivity causes 10% to 16% of cases each of breast cancer, colon, and rectal cancers as well as type 2 diabetes, and 22% of coronary heart disease and the burden of these and other chronic diseases has rapidly increased in recent decades. OBJECTIVES The purpose of this systematic review was to summarize the evidence of the effectiveness of school-based interventions in promoting physical activity and fitness in children and adolescents. SEARCH METHODS The search strategy included searching several databases to October 2011. In addition, reference lists of included articles and background papers were reviewed for potentially relevant studies, as well as references from relevant Cochrane reviews. Primary authors of included studies were contacted as needed for additional information. SELECTION CRITERIA To be included, the intervention had to be relevant to public health practice (focused on health promotion activities), not conducted by physicians, implemented, facilitated, or promoted by staff in local public health units, implemented in a school setting and aimed at increasing physical activity, included all school-attending children, and be implemented for a minimum of 12 weeks. In addition, the review was limited to randomized controlled trials and those that reported on outcomes for children and adolescents (aged 6 to 18 years). Primary outcomes included: rates of moderate to vigorous physical activity during the school day, time engaged in moderate to vigorous physical activity during the school day, and time spent watching television. Secondary outcomes related to physical health status measures including: systolic and diastolic blood pressure, blood cholesterol, body mass index (BMI), maximal oxygen uptake (VO2max), and pulse rate. DATA COLLECTION AND ANALYSIS Standardized tools were used by two independent reviewers to assess each study for relevance and for data extraction. In addition, each study was assessed for risk of bias as specified in the Cochrane Handbook for Systematic Reviews of Interventions. Where discrepancies existed, discussion occurred until consensus was reached. The results were summarized narratively due to wide variations in the populations, interventions evaluated, and outcomes measured. MAIN RESULTS In the original review, 13,841 records were identified and screened, 302 studies were assessed for eligibility, and 26 studies were included in the review. There was some evidence that school-based physical activity interventions had a positive impact on four of the nine outcome measures. Specifically positive effects were observed for duration of physical activity, television viewing, VO2 max, and blood cholesterol. Generally, school-based interventions had little effect on physical activity rates, systolic and diastolic blood pressure, BMI, and pulse rate. At a minimum, a combination of printed educational materials and changes to the school curriculum that promote physical activity resulted in positive effects.In this update, given the addition of three new inclusion criteria (randomized design, all school-attending children invited to participate, minimum 12-week intervention) 12 of the original 26 studies were excluded. In addition, studies published between July 2007 and October 2011 evaluating the effectiveness of school-based physical interventions were identified and if relevant included. In total an additional 2378 titles were screened of which 285 unique studies were deemed potentially relevant. Of those 30 met all relevance criteria and have been included in this update. This update includes 44 studies and represents complete data for 36,593 study participants. Duration of interventions ranged from 12 weeks to six years.Generally, the majority of studies included in this update, despite being randomized controlled trials, are, at a minimum, at moderate risk of bias. The results therefore must be interpreted with caution. Few changes in outcomes were observed in this update with the exception of blood cholesterol and physical activity rates. For example blood cholesterol was no longer positively impacted upon by school-based physical activity interventions. However, there was some evidence to suggest that school-based physical activity interventions led to an improvement in the proportion of children who engaged in moderate to vigorous physical activity during school hours (odds ratio (OR) 2.74, 95% confidence interval (CI), 2.01 to 3.75). Improvements in physical activity rates were not observed in the original review. Children and adolescents exposed to the intervention also spent more time engaged in moderate to vigorous physical activity (with results across studies ranging from five to 45 min more), spent less time watching television (results range from five to 60 min less per day), and had improved VO2max (results across studies ranged from 1.6 to 3.7 mL/kg per min). However, the overall conclusions of this update do not differ significantly from those reported in the original review. AUTHORS' CONCLUSIONS The evidence suggests the ongoing implementation of school-based physical activity interventions at this time, given the positive effects on behavior and one physical health status measure. However, given these studies are at a minimum of moderate risk of bias, and the magnitude of effect is generally small, these results should be interpreted cautiously. Additional research on the long-term impact of these interventions is needed.

Abstract
BACKGROUND African Americans are disproportionately affected by cardiovascular disease and cancer. Health promotion interventions hold promise for reducing health disparities. PURPOSE Promoting Health Among Teens (PHAT) is a brief, culturally tailored health education intervention to decrease cardiovascular disease and cancer risk for African Americans. This study evaluated the effects of PHAT for African American adolescents ages 14 to 17 in four eastern cities in the USA. METHODS A randomized controlled design (N = 1,654) was used to determine differences in health knowledge, diet, physical activity, and substance use behaviors between PHAT participants and a sexual health promotion control group. Data were collected at baseline, three, six, and twelve months post intervention. Growth curve modeling was used to detect differences in health knowledge, dietary behaviors, physical activity, and substance use between PHAT and control group participants. RESULTS PHAT participants had significantly greater knowledge gains but modest behavior changes compared to control group participants. DISCUSSION PHAT is a promising intervention to increase knowledge and address selected health behaviors in African American youth. TRANSLATION TO HEALTH EDUCATION PRACTICE Future attempts to execute PHAT should continue its emphasis on knowledge building while increasing intervention dosage and modifying length of time for intervention sessions.

Abstract
BACKGROUND The World Health Organization estimates that 1.9 million deaths worldwide are attributable to physical inactivity. Chronic diseases associated with physical inactivity include cancer, diabetes and coronary heart disease. OBJECTIVES The purpose of this systematic review is to summarize the evidence of the effectiveness of school-based interventions in promoting physical activity and fitness in children and adolescents. SEARCH STRATEGY The search strategy included searching several databases. In addition, reference lists of included articles and background papers were reviewed for potentially relevant studies, as well as references from relevant Cochrane reviews. Primary authors of included studies were contacted as needed for additional information. SELECTION CRITERIA To be included, the intervention had to be relevant to public health practice, implemented, facilitated, or promoted by staff in local public health units, implemented in a school setting and aimed at increasing physical activity, report on outcomes for children and adolescents (aged 6 to 18 years), and use a prospective design with a control group. DATA COLLECTION AND ANALYSIS Standardized tools were used by two independent reviewers to rate each study's methodological quality and for data extraction. Where discrepancies existed discussion occurred until consensus was reached. The results were summarized narratively due to wide variations in the populations, interventions evaluated and outcomes measured. MAIN RESULTS 13,841 titles were identified and screened and 482 articles were retrieved. Multiple publications on the same project were combined and counted as one project, resulting in 395 distinct project accounts (studies). Of the 395 studies 104 were deemed relevant and of those, four were assessed as having strong methodological quality, 22 were of moderate quality and 78 were considered weak. In total 26 studies were included in the review. There is good evidence that school-based physical activity interventions have a positive impact on four of the nine outcome measures. Specifically positive effects were observed for duration of physical activity, television viewing, VO2 max, and blood cholesterol. Generally school-based interventions had no effect on leisure time physical activity rates, systolic and diastolic blood pressure, body mass index, and pulse rate. At a minimum, a combination of printed educational materials and changes to the school curriculum that promote physical activity result in positive effects. AUTHORS' CONCLUSIONS Given that there are no harmful effects and that there is some evidence of positive effects on lifestyle behaviours and physical health status measures, ongoing physical activity promotion in schools is recommended at this time.

Abstract
Diabetes mellitus is escalating globally and it is predicted that 200 million individuals worldwide will have diabetes by 2010 and 300 million by 2025. However, there is compelling evidence from many studies that for subjects with impaired fasting glucose or impaired glucose tolerance the presentation of type 2 diabetes can be delayed by lifestyle modification. The aim of the present review is to present a summary of lifestyle modification interventions that have included a dietary component in their overall diabetes prevention programme. Medline, allied health literature and diabetes journals were searched for peer-reviewed literature using the terms 'diet*' and 'diabetes' and 'intervention'. Inclusion criteria were: peer-reviewed studies from 1975 to 2008; a sample of at least fifty subjects; a healthy eating and/or physical activity component; prevention of diabetes as a primary goal. Generally, the participants were in a high-risk category for the development of diabetes. Outcomes were evaluated at two points in time (pre- and post-intervention) in terms of knowledge, behaviour change and clinical improvement, which included weight, blood pressure, BMI, body fat, waist circumference, waist:hip ratio and physiological and/or biochemical measures. Findings indicate that the most successful interventions combine individual dietary counselling with an activity component. Further factors predicting success are weight loss achieved, duration and intensity of the intervention and dietary compliance.

Abstract
Type 2 diabetes mellitus (T2DM) affects more than 7% of adults in the US and leads to substantial personal and economic burden. In prediabetic states insulin secretion and action--potential targets of preventive interventions--are impaired. In trials lifestyle modification (i.e. weight loss and exercise) has proven effective in preventing incident T2DM in high-risk groups, although weight loss has the greatest effect. Various medications (e.g. metformin, thiazolidinediones and acarbose) can also prevent or delay T2DM. Whether diabetes-prevention strategies also ultimately prevent the development of diabetic vascular complications is unknown, but cardiovascular risk factors are favorably affected. Preventive strategies that can be implemented in routine clinical settings have been developed and evaluated. Widespread application has, however, been limited by local financial considerations, even though cost-effectiveness might be achieved at the population level.

Abstract
BACKGROUND Recommendations for physical activity in the Guide to Community Preventive Services (the Community Guide) have not been systematically examined or applied in developing countries such as those in Latin America. The aim of this systematic review was to assess the current evidence base concerning interventions to increase physical activity in Latin America using a modified Community Guide process and to develop evidence-based recommendations for physical activity interventions. METHODS In 2006, a literature review of both peer-reviewed and non-peer-reviewed literature in Portuguese, Spanish, and English was carried out to identify physical activity interventions conducted in community settings in Latin America. Intervention studies were identified by searching ten databases using 16 search terms related to physical activity, fitness, health promotion, and community interventions. All intervention studies related to physical activity were summarized into tables. Six reviewers independently classified the intervention studies by the categories used in the Community Guide and screened the studies for inclusion in a systematic abstraction process to assess the strength of the evidence. Five trained researchers conducted the abstractions. RESULTS The literature search identified 903 peer-reviewed articles and 142 Brazilian theses related to physical activity, of which 19 were selected for full abstraction. Only for school-based physical education classes was the strength of the evidence from Latin America sufficient to support a practice recommendation. CONCLUSIONS This systematic review highlights the need for rigorous evaluation of promising interventions to increase physical activity in Latin America. Implementation and maintenance of school physical education programs and policies should be strongly encouraged to promote the health of Latin American children.

Abstract
The literature regarding the prevention of diabetes provides few standards for community-based initiatives. The present article offers four principles for engaging communities in comprehensive community approaches to diabetes prevention including (1) facilitating meaningful and central roles for communities, (2) giving primary attention to participatory processes rather than to best practices, (3) emphasizing cultural relevance in designing interventions particularly in racial and ethnic communities, and (4) incorporating social ecology approaches that are holistic and that address larger environmental influences rather than individual behavioral change alone. In order that community public health practitioners may operationalize the principles, models are provided for each.

Abstract
Childhood obesity is a global epidemic and rising trends in overweight and obesity are apparent in both developed and developing countries. Available estimates for the period between the 1980s and 1990s show the prevalence of overweight and obesity in children increased by a magnitude of two to five times in developed countries (e.g. from 11% to over 30% in boys in Canada), and up to almost four times in developing countries (e.g. from 4% to 14% in Brazil). The goal of this synthesis research study was to develop best practice recommendations based on a systematic approach to finding, selecting and critically appraising programmes addressing prevention and treatment of childhood obesity and related risk of chronic diseases. An international panel of experts in areas of relevance to obesity provided guidance for the study. This synthesis research encompassed a comprehensive search of medical/academic and grey literature and the Internet covering the years 1982-2003. The appraisal approach developed to identify best practice was unique, in that it considered not only methodological rigour, but also population health, immigrant health and programme development/evaluation perspectives in the assessment. Scores were generated based on pre-determined criteria with programmes scoring in the top tertile of the scoring range in any one of the four appraisal categories included for further examination. The synthesis process included identification of gaps and an analysis and summary of programme development and programme effectiveness to enable conclusions to be drawn and recommendations to be made. The results from the library database searches (13,158 hits), the Internet search and key informant surveys were reduced to a review of 982 reports of which 500 were selected for critical appraisal. In total 158 articles, representing 147 programmes, were included for further analysis. The majority of reports were included based on high appraisal scores in programme development and evaluation with limited numbers eligible based on scores in other categories of appraisal. While no single programme emerged as a model of best practice, synthesis of included programmes provided rich information on elements that represent innovative rather than best practice under particular circumstances that are dynamic (changing according to population subgroups, age, ethnicity, setting, leadership, etc.). Thus the findings of this synthesis review identifies areas for action, opportunities for programme development and research priorities to inform the development of best practice recommendations that will reduce obesity and chronic disease risk in children and youth. A lack of programming to address the particular needs of subgroups of children and youth emerged in this review. Although immigrants new to developed countries may be more vulnerable to the obesogenic environment, no programmes were identified that specifically targeted their potentially specialized needs (e.g. different food supply in a new country). Children 0-6 years of age and males represented other population subgroups where obesity prevention programmes and evidence of effectiveness were limited. These gaps are of concern because (i) the pre-school years may be a critical period for obesity prevention as indicated by the association of the adiposity rebound and obesity in later years; and (ii) although the growing prevalence of obesity affects males and females equally; males may be more vulnerable to associated health risks such as cardiovascular disease. Other gaps in knowledge identified during synthesis include a limited number of interventions in home and community settings and a lack of upstream population-based interventions. The shortage of programmes in community and home settings limits our understanding of the effectiveness of interventions in these environments, while the lack of upstream investment indicates an opportunity to develop more upstream and population-focused interventions to balance and extend the current emphasis on individual-based programmes. The evidence reviewed indicates that current programmes lead to short-term improvements in outcomes relating to obesity and chronic disease prevention with no adverse effects noted. This supports the continuation and further development of programmes currently directed at children and youth, as further evidence for best practice accumulates. In this synthesis, schools were found to be a critical setting for programming where health status indicators, such as body composition, chronic disease risk factors and fitness, can all be positively impacted. Engagement in physical activity emerged as a critical intervention in obesity prevention and reduction programmes. While many programmes in the review had the potential to integrate chronic disease prevention, few did; therefore efforts could be directed towards better integration of chronic disease prevention programmes to minimize duplication and optimize resources. Programmes require sustained long-term resources to facilitate comprehensive evaluation that will ascertain if long-term impact such as sustained normal weight is maintained. Furthermore, involving stakeholders in programme design, implementation and evaluation could be crucial to the success of interventions, helping to ensure that needs are met. A number of methodological issues related to the assessment of obesity intervention and prevention programmes were identified and offer insight into how research protocols can be enhanced to strengthen evidence for obesity interventions. Further research is required to understand the merits of the various forms in which interventions (singly and in combination) are delivered and in which circumstances they are effective. There is a critical need for the development of consistent indicators to ensure that comparisons of programme outcomes can be made to better inform best practice.

Abstract
In order to evaluate the need for preventive interventions to improve nutrition, the BMI/sex/age percentile, height/sex/age percentile, prevalence of stunting, at-risk-for-overweight and overweight in a group of migrant Hispanic children, aged 2-18, in southern New Jersey, USA, was assessed using anthropometric measurements of height, weight and skinfold thickness with reference to the NHANES 1999-2000. Results showed that the frequency of overweight in this sample--20%--exceeds that of the general U.S. pediatric population and equals or exceeds (in 2-5-year olds) that of settled Mexican-Americans. Being born in the U.S. significantly diminished the prevalence of stunting, especially in boys. The children of migrant Hispanic agricultural workers belong to a marginalized, poor and insecure population who are not included in the National Health and Nutrition Examination studies, because of their transience. This is the first anthropometric study to evaluate growth in this population in over 20 years.

Abstract
OBJECTIVES Report the 8-year impact on body size, physical activity, and diet of a community-based diabetes prevention program for elementary-school children in a Kanien'keha:ka (Mohawk) community in Canada. METHODS Follow-up (1994-1996) of subjects in the intervention and comparison community and repeat cross-sectional measurements in the intervention community alone from 1994 to 2002. Measures included triceps and subscapular skinfold thicknesses, body mass index (BMI), weekly number of 15-minute episodes of physical activity, run/walk test times, television watching, and consumption of sugared foods, fatty foods, and fruits and vegetables. RESULTS The longitudinal data of 1994-1996 showed some early positive effects of the program on skinfold thickness but not on BMI, physical activity, fitness, or diet. Repeat cross-sectional measures from 1994 to 2002 showed increases in skinfold thickness and BMI. Physical activity, fitness, and television watching showed favorable trends from 1994 to 1999 that were not sustained in 2002. Key high-fat and high-sugar foods consumption decreased, as did consumption of fruits and vegetables. CONCLUSIONS Although early results showed some successes in reducing risk factors for type 2 diabetes, these benefits were not maintained over 8 years.

Abstract
Abstract Type 2 Diabetes mellitus (T2DM) is a complex metabolic, multifactorial disease, which affects the quality, quantity and style of life. People with T2DM have a life expectancy that can be shortened by as much as 15 years, with up to 75% dying of macrovascular complications. To reduce the impact of T2DM in the 21st century, we need an approach that not only optimally treats the person with established diabetes but also prevents diabetes from occurring in the first place. The best evidence for prevention of diabetes is for interventions that target individuals at highest risk. Targeting patients who have impaired glucose tolerance with lifestyle changes including physical activity and dietary factors has been shown to be effective in the Chinese, North American and Finnish populations. In order for such lifestyle interventions to be successful in other populations, they need to be culturally sensitive, individualized and sustained. Some pharmacological agents including metformin and acarbose have also been shown to be effective, although the profile of those who respond is different. There continues to be a need to develop and evaluate interventions that target communities and populations at risk in a UK setting.

Abstract
Diabetes, a serious public health problem, is on the rise, claiming millions of victims. A considerable body of research exists on diabetes, but the development of effective primary prevention strategies is just beginning. This article presents the results of a project, based on an innovative approach where health professionals and community groups have come together to address the issue. The purpose of the project is to develop an intervention strategy for the prevention of type 2 diabetes directed at young francophones living in a minority environment in New Brunswick and adapted to their needs. Qualitative data were gathered from two focus groups and submitted for a content analysis. The process was evaluated. The young francophones have identified the school environment as ideal for intervention. According to them, the intervention should be adapted to the age of the youths. For the 5-to-13-year-old group, the intervention should target healthy eating habits and physical activity whereas for the 14-to-18-year-old group, the emphasis should be on preventing diabetes. The youth and the professionals acquired a greater understanding of the problem of diabetes and its prevention. Youth can now proceed to action, with appropriate guidance. The experience and knowledge of the professionals contributed to the development of the strategy. A shortage of dietitians in public health to work in the area of the prevention of diabetes has been noted.

Abstract
PURPOSE This article proposes a model grounded in behavioral theory and empirical evidence for use when developing a program to prevent type 2 diabetes in high-risk minority youth. METHODS The model is based on key concepts of 4 behavioral theories: the Health Belief Model, Social Learning Theory, the Theory of Planned Behavior, and the Ecological Model. Determinants of behavior to target for change are selected based on their theoretical link to behavior change, their success in changing behavior in past programs, and through thorough formative research in the target community. RESULTS Diabetes prevention in children requires modifying a complex set of behavior patterns. Social norms and the environment are especially important in children in whom cognitive processes have not fully developed. Family and community involvement is essential for developing a health program and providing a supportive environment in which to change behavior and ongoing reinforcement to maintain behavior changes. CONCLUSIONS Behavioral theory informs the selection of factors to target in a behavioral intervention. Special considerations apply when working with children. A program to target risk must be based in behavioral theory, supported by practical data, and tailored to the needs and beliefs of the target community.

Abstract
OBJECTIVE To conduct a literature review of community-based interventions intended to prevent or delay type 2 diabetes. RESEARCH DESIGN AND METHODS Recently published findings about the potential to prevent or delay type 2 diabetes with intensive lifestyle interventions prompted a literature search for community-based diabetes prevention interventions. The literature review design was a search of databases for publications in 1990-2001 that identified reports on community-based interventions designed to prevent or modify risk factors for type 2 diabetes. RESULTS The search revealed 16 published interventions, 8 of which were conducted in the U.S. and involved populations disproportionately burdened by diabetes (e.g., American Indians, Native Hawaiians, Mexican Americans, and African Americans). Of the studies reporting results among youth, there were posttest improvements in intervention groups in knowledge, preventive behaviors, and self-esteem. Among studies reporting results among adults, most reported improvements in intervention groups in knowledge or adoption of regular physical activity. Several investigators offered important reflections about the process of engaging communities and sharing decision making in participatory research approaches, as well as insights about the expectations and limitations of community-based diabetes prevention research. Many of the studies reported limitations in their design, including the lack of control or comparison groups, low response rates or lack of information on nonresponders, or brief intervention periods. CONCLUSIONS There is a critical need to conduct and publish reports on well-designed community-based diabetes prevention research and share information on the process, results, and lessons learned. Armed with recent positive findings about diabetes prevention and literature documenting community-based efforts, advocates at local, state, and national levels can collaborate to stem the rising tide of diabetes in communities.

Abstract
Type 2 diabetes in youth is an increasing public health concern, especially in certain minority populations. The current paper consists of four sections. First, we establish the significance of the problem by presenting an overview of epidemiological and physiological evidence. Second, we discuss behavioral issues relevant to the prevention of type 2 diabetes in youth. Third, a qualitative review of existing prevention interventions specific to type 2 diabetes in youth is presented. Results suggest that modest improvements in social cognitive, dietary, and exercise outcomes are possible with diabetes intervention studies, although beneficial changes are difficult to sustain over the long term. Although theoretical frameworks are not always explicit, most studies have utilized elements of the social cognitive theory. Less attention has been paid to sociocultural and community organization variables. Finally, the paper discusses issues of risk definition and intervention sustainability, and presents a comprehensive, theoretically diverse model for the prevention of type 2 diabetes in youth. In summary, we suggest that theories of the natural history and pathophysiology of type 2 diabetes are important to identify modifiable risk factors, while theories of behavioral change are essential to modify the risk factors identified. The combination of sound physiological and behavioral theories should form the basis of prevention intervention design. In addition, an ecologic approach that takes into consideration the dynamic interactions of personal, social, and environmental factors would best promote the long-term adoption of healthful behaviors in a supportive, meaningful, and personally enjoyable context.

Abstract
OBJECTIVE To assess the risk factors for a group of children at high risk for type 2 diabetes using a proven medical model and incorporating a community-friendly standardized fitness assessment tool. DESIGN All children in school (kindergarten to grade eight) in an isolated First Nation community were enrolled to be screened for diabetes, risk factors, and fitness level. SETTING Beausoleil First Nation community is an Ojibway community situated on Christian Island in Georgian Bay, Ontario, Canada. PARTICIPANTS All children attending Christian Island Elementary School, a total of 101 students from kindergarten to grade eight. INTERVENTIONS Capillary blood glucose fasting and 2 hours after 75-g simple carbohydrate meal, height and weight (calculated BMI), blood pressure, aerobic capacity, abdominal strength and endurance, upper body strength, trunk extensor strength and flexibility, and upper body flexibility. OUTCOME MEASUREMENTS Applicability of tests to assess disease, risk factors, and fitness level. RESULTS Eight children were found to have abnormal capillary blood glucose and required further laboratory investigations. Significant risk factors for type 2 diabetes were identified. The screening exercise assessment identified specific areas below that considered a healthy fitness zone. CONCLUSIONS The screening assessment identified medical areas of concern in capillary blood glucose, blood pressure, and body mass index. The fitness testing identified areas of concern in aerobic capacity, upper body strength, abdominal strength and endurance, and flexibility. The fitness testing was First Nation community-friendly.

Abstract
Childhood obesity may be seen as a marker for high-risk dietary and physical inactivity practices. Recent increases in the prevalence of overweight and obesity among American children are not limited to one age, gender, or ethnic group, which suggests that unique behaviors of the members of various racial or ethnic subgroups of the population are unlikely to be the major contributing factors. Rather, it seems that environmental changes promoting increased energy intake and decreased energy output are occurring and have widespread impact on children from various backgrounds. Although no ethnic group is immune from the current shift in energy balance, differential rates of overweight seem to exist among ethnic groups. National probability samples of African-American, Hispanic, and white children in the United States provide clear evidence that white children are at lower risk for childhood overweight than are African-American or Hispanic children. Of concern is the lack of national data on the prevalence of overweight and obesity for Native-American and Asian-American groups. Also of concern is the aggregation of racial and ethnic subgroups, which may render prevalence rates meaningless. This possibility is clearly true with some surveys of weight status that combine diverse populations, such as Asians and Pacific Islanders, into one group. The high rates of obesity in African-American, Hispanic, and Native-American children are of concern. Although parental SES is associated inversely with childhood obesity among whites, higher SES does not seem to protect African-American and Hispanic children against obesity. In these groups, childhood obesity does not seem to be associated significantly with parental income and education. Health consequences of childhood obesity include a higher prevalence of type 2 diabetes and an increased risk for adverse levels of lipids, lipoproteins, and blood pressure. The effects of recently reported unprecedented levels of childhood overweight on subsequent risk for obesity in middle age are not known until future longitudinal data can be collected. It seems likely, however, that future health consequences of current early and severe childhood obesity will be staggering. Funding for adult follow-up of longitudinal studies of high-risk African American, Hispanic, and Native-American children is needed urgently to provide information on the long-term effects of childhood obesity. Halting the obesity epidemic is a formidable task, but the success in recent decades of drastically reducing childhood undernutrition offers hope and should spur similar action and leadership efforts. Promotion of efforts to reduce excess caloric intake with efforts to increase energy expenditure should receive paramount attention in the design of health programs. Given the relatively few published obesity-prevention and treatment studies that are designed to address specific cultural issues, it is important to promote the development of culturally appropriate intervention strategies that are shown to be effective among youth of diverse backgrounds. Although the dietary and activity goals will be similar, parental, family, and community messages and techniques grounded in cultural traditions and norms will be different for each ethnic group. This approach is crucial in the United States, a country with an increasingly diverse population.

Abstract
The incidence of type 2 diabetes is increasing in the United States, and minority populations in particular seem to be affected. In the past, it was thought that type 2 diabetes occurred only in adults. However, an alarming epidemic has emerged, and children as young as 8 years of age are now being diagnosed with the disease. The purpose of this article is to present pediatric nurse practitioners with the most recent information about type 2 diabetes in children and adolescents, summarize current understanding about diagnosis, and outline treatment options.
