Evaluation of a culturally appropriate smoking cessation intervention for Latinos.

BACKGROUND: Many believe that smoking cessation programmes for Latinos should be tailored to the values and beliefs of the culture. However, randomised studies of culturally appropriate smoking cessation interventions with Latinos are rare. METHODS: Latino smokers (n = 313) were randomised to an intervention condition or a comparison group. The intervention was a three month programme based on social cognitive constructs and delivered in the smoker's home by trained lay health advisors, or promotores. Comparison group participants were referred to the California Smoker's Helpline in Spanish. Predictors of abstinence among all participants also were examined. RESULTS: About one week post-intervention, validated (carbon monoxide) past week abstinence rates were more than twice as high in the intervention group (20.5%) than in the comparison (8.7%) (p < or = 0.005). The pattern of results held for self reported abstinence, and after recoding dropouts to non-abstinence. The primary predictor of abstinence was number of cigarettes smoked per day at baseline, a common measure of addiction. CONCLUSIONS: The culturally appropriate intervention facilitated abstinence in Latino smokers, at least in the short term. Strengths and weaknesses of the study are discussed.

Evaluation of a first aid and home safety program for Hispanic migrant adolescents.

BACKGROUND: Unintentional injuries are the major cause of death among children, adolescents, and young adults. This article presents an evaluation of an injury-prevention program for 11- to 16-year-old, Hispanic migrant youth. DESIGN: Randomized controlled trial with two conditions: first aid and home safety training and tobacco and alcohol prevention. Participants were assessed at baseline, at immediate post-intervention, and at 1-year follow-up. PARTICIPANTS: A total of 660 Hispanic adolescent and parent pairs participated in a program entitled Sembrando Salud (sowing the seeds of health). INTERVENTION: The intervention consisted of two conditions: first aid and home safety training and tobacco and alcohol prevention. Both groups were exposed to an eight-session, multimedia program presented by bilingual, bicultural college students. The sessions consisted of lectures, discussions, and skills development and practice. OUTCOME MEASURES: To examine the efficacy of the first aid and home safety intervention, adolescents were assessed for changes in first aid confidence, knowledge of items in a first aid kit, knowledge of how to respond in an emergency situation, acquisition of a first aid kit, and behavioral skills testing in response to two emergency scenarios. RESULTS: Similar changes in confidence were observed in both groups after the intervention. Participants in the first aid and home safety program were better able to identify items to include in a first aid kit, how to respond in an emergency situation, and reported fewer erroneous victim-caring procedures than the tobacco and alcohol prevention group. CONCLUSIONS: Sembrando Salud was successful at achieving and maintaining change in confidence and knowledge of first aid and emergency response skills over a yearlong period.

Nutrition communication for a Latino community: formative research foundations.

Formative research techniques were used to develop a tailored health communication nutrition intervention for Latinas and their families. Members of the target community were recruited to participate in focus groups, depth interviews, and participant observations. Women, in particular, were observed preparing meals in their homes and purchasing groceries. The objective was to identify variables that could be used for targeting, segmenting, and tailoring the intervention. Results from these efforts were used to develop a theory-based intervention, which is described at the conclusion of the article.

Predictors of cigarette and alcohol susceptibility and use among Hispanic migrant adolescents.

BACKGROUND: Little is known about interpersonal and broader sociocultural factors related to protection from or use of tobacco and alcohol among immigrant adolescents. This study presents the baseline predictors of tobacco and alcohol use and susceptibility to tobacco and alcohol among Hispanic migrant adolescents. METHODS: The sample consisted of 660 Hispanic adolescents (51% male) between the ages of 11 and 16 years enrolled in the Migrant Education Program through the County Office of Education. Slightly more than 75% of the study sample was first generation Hispanics and 79% preferred to speak Spanish. An interviewer-administered survey assessed the following information: standard demographic characteristics, modeling of cigarette smoking (including parental and peer smoking), attitudes (including self-standards and anticipated outcomes), acculturation, communication with parents, amount of social support, and satisfaction with social support. RESULTS: Significant predictors of susceptibility to tobacco and smoking status included age, gender, attitudes toward cigarettes (e.g., anticipated outcomes, self-standards), satisfaction with social support, and parent-child communication. Factors that were also significant predictors of susceptibility to alcohol and drinking status were age, attitudes toward drinking, satisfaction with social support, and level of parent-child communication. In addition, peer and household use of alcohol predicted adolescent outcomes. CONCLUSIONS: Based on these results it is suggested that tobacco and alcohol prevention efforts for first-generation Hispanic adolescents should target not only usual concerns (e.g., availability, peer pressure, modeling, expectancies), but also parent-child communication.

Evaluation of a tobacco and alcohol use prevention program for Hispanic migrant adolescents: promoting the protective factor of parent-child communication.

BACKGROUND: Interventions designed to prevent tobacco and alcohol use targeting high-risk adolescents are limited. In addition, few studies have attempted to improve parent-child communication skills as a way of improving and maintaining healthy youth decision-making. METHODS: A total of 660 Hispanic migrant families participated in a randomized pre-post control group study that was utilized to determine the impact of the intervention on parent-child communication. Both treatment and attention-control groups of youth were exposed to an eight-session culturally sensitive program presented by bilingual/bicultural college students. Parents jointly attended three of the eight sessions and participated in helping their child complete homework assignments supporting the content of each session. The content of the treatment intervention included (1) information about tobacco and alcohol effects, (2) social skills training (i.e., refusal skills), and (3) the specific development of parent-child communication skills to support healthy youth decisions. RESULTS: Significant intervention by household size interactions for both parent and youth perceptions of communication were found indicating that the treatment was effective in increasing communication in families with fewer children. Based on the effect size and the previously established relationship between communication and susceptibility to tobacco and alcohol use, it was determined that the intervention effect could be translated into a future 5 to 10% decrease in susceptibility for these smaller families. CONCLUSIONS: A culturally sensitive family-based intervention for migrant Hispanic youth was found to be effective in increasing perceived parent-child communication in families with fewer children. It is expected that increases in this important protective factor will lead to later observed decreases in tobacco and alcohol use.

Patient reminder letters to promote annual mammograms: a randomized controlled trial.

BACKGROUND: This study assessed the effects of a reminder letter from a physician (relative to a mammography facility letter or no letter) on appointment compliance among women 50-74 years of age due for an annual screening mammogram. METHODS: A total of 1,562 women were randomly as signed to the groups. Each Group 1 subject received a reminder letter from her physician, each Group 2 subject received a reminder letter from her mammography facility, and Group 3 served as a control group. RESULTS: The return rates for Groups 1, 2, and 3 were 47.7, 46.6, and 28.3%, respectively; the overall difference was significant using a chi(2) analysis (P < 0.001). Bonferroni pairwise comparisons indicated no difference between Groups 1 and 2 but significant differences (P < 0.001) between Group 3 and the other two groups. Logistic regression indicated that relative to Group 3, the adjusted odds of returning for Groups 1 and 2 were 2.37 and 2.24, respectively. CONCLUSIONS: Mammography providers and their patients likely will benefit from in-reach reminder systems. Physicians who do not use reminder systems should refer their patients to facilities that use these systems.

Fat and sugar levels are high in snacks purchased from student stores in middle schools.

OBJECTIVE: Children consume about one third of their daily energy at school, mostly from cafeteria food and bag lunches. Students also shop at student-run stores that generate revenue for extracurricular activities; yet the nutritional value of snacks sold at student stores has not been documented to our knowledge. DESIGN: Cross-sectional study of foods sold at student stores in middle schools. SUBJECTS/SETTING: Twenty-four San Diego County (Calif) public middle schools, grades 6 through 8 (age 11 to 13), from 9 school districts. The schools represent a diversity of ethnic groups and socioeconomic levels. STATISTICAL ANALYSES PERFORMED: Descriptive statistics, Pearson product moment correlations, analysis of variance. RESULTS: Snacks averaged 8.7 g fat and 23.0 g sugar. Overall, 88.5% of store inventory was high in fat and/or high in sugar. Sugar candy accounted for one third of store sales. Chocolate candy was highest in fat content: 15.7 g. Fourteen of the 24 schools had stores that sold food and were run by student organizations. Stores were open daily for about 90 minutes; half sold food during lunch. CONCLUSIONS: Adolescents need opportunities to supplement main meals; however, student stores in middle schools sell primarily high-fat, high-sugar snacks. Key intervention possibilities include limiting sales of chocolate candy and substituting low-fat varieties of cakes, cookies, chips, and crackers. Competition with cafeterias for sales at lunchtime should be addressed.

A national survey of sun safety activities at U.S. zoos.

Skin cancer incidence in the United States has increased. Exposure to ultraviolet radiation (UVR) is a major risk factor for skin cancer. Every year, millions of children with their families visit outdoor leisure facilities such as zoos where overexposure to UVR may occur. This study was conducted to assess the proportion of U.S. zoos that provided sun safety activities during the summer of 1998 and their willingness to incorporate skin cancer prevention strategies at their facility in the future. A 56 item self-administered questionnaire was mailed to 140 zoos accredited by the American Zoo and Aquarium Association. A follow-up telephone survey was also conducted with 33 mail non-respondents. The response rate was 97% (N = 136). Results revealed that in the summer of 1998, only 5% of zoos provided sun safety recommendations to visitors and 25% of zoos provided recommendations to their employees. The recommendations made most often to visitors and employees were to use sunscreen and wear protective clothing. Eighty-five percent of zoos indicated interest in providing sun safety activities at their facilities in the future. The next step will be to design environmentally appropriate sun safety programs for zoos and to encourage zoos to implement these programs.

Results of language for health: cardiovascular disease nutrition education for Latino English-as-a-second-language students.

This report presents the final evaluation of Language for Health, part of a federally funded initiative to develop heart disease prevention interventions for low-literate populations. Language for Health specifically intervened with recent immigrants enrolled in English-as-a-second-language classes, incorporating nutritional behavior change materials into English-language curricula. Latino participants (n = 732) were exposed to either nutrition education or stress management classes (attention-placebo group) designed specifically for low-English-literate adults. Participants completed physiological measures assessing blood pressure, total and high-density lipoprotein (HDL) cholesterol, waist and hip circumference, and weight. Self-report surveys were administered to collect students' nutrition-related knowledge, attitudes, self-reported fat avoidance behaviors, and demographic information. Data were collected at baseline, 3-month posttest, and 6-month follow-up. Results indicated long-term effects of the intervention on nutrition knowledge and fat avoidance, yet only short-term effects on total cholesterol:HDL ratio and systolic blood pressure.

Three-year maintenance of improved diet and physical activity: the CATCH cohort. Child and Adolescent Trial for Cardiovascular Health.

OBJECTIVE: To assess differences through grade 8 in diet, physical activity, and related health indicators of students who participated in the Child and Adolescent Trial for Cardiovascular Health (CATCH) school and family intervention from grades 3 through 5. DESIGN: Follow-up of the 4-center, randomized, controlled field trial with 56 intervention and 40 control elementary schools. PARTICIPANTS: We studied 3714 (73%) of the initial CATCH cohort of 5106 students from ethnically diverse backgrounds in California, Louisiana, Minnesota, and Texas at grades 6, 7, and 8. RESULTS: Self-reported daily energy intake from fat at baseline was virtually identical in the control (32.7%) and intervention (32.6%) groups. At grade 5, the intake for controls remained at 32.2%, while the intake for the intervention group declined to 30.3% (P<.001). At grade 8, the between-group differential was maintained (31.6% vs 30.6%, P = .01). Intervention students maintained significantly higher self-reported daily vigorous activity than control students (P = .001), although the difference declined from 13.6 minutes in grade 5 to 11.2, 10.8, and 8.8 minutes in grades 6, 7, and 8, respectively. Significant differences in favor of the intervention students also persisted at grade 8 for dietary knowledge and dietary intentions, but not for social support for physical activity. No impact on smoking behavior or stages of contemplating smoking was detected at grade 8. No significant differences were noted among physiologic indicators of body mass index, blood pressure, or serum lipid and cholesterol levels. CONCLUSION: The original CATCH results demonstrated that school-level interventions could modify school lunch and school physical education programs as well as influence student behaviors. This 3-year follow-up without further intervention suggests that the behavioral changes initiated during the elementary school years persisted to early adolescence for self-reported dietary and physical activity behaviors.

Theories and intervention approaches to health-behavior change in primary care.

CONTENT: Providers typically rely on health information and their professional status to convince patients to change. Health-behavior theories and models suggest more effective methods for accomplishing patient compliance and other behavior change related to treatment regimens. Behavior modification stresses the remediation of skill deficits or using positive and negative reinforcement to modify performance. Like behavior modification, the Health Belief Model stresses a reduction of environmental barriers to behavior. Social Learning Theory suggests that perceptions of skills and reinforcement may more directly determine behavior. Self-management models put the above theories into self-change actions. Social support theories prioritize reinforcement delivered through social networks, whereas the Theory of Reasoned Action emphasizes perceptions of social processes. Finally, the Transtheoretical Model speaks of the necessity to match interventions to cognitive-behavioral stages. Strategies derived from each of these theories are suggested herein.

Pretesting Spanish-language educational radio messages to promote timely and complete infant immunization in California.

California's Hispanic infants have lower immunization levels than non-Latino white infants, 53.7% versus 65.2%, respectively. Spanish-language radio is an effective mass media venue for imparting information to Latino populations. It has been demonstrated that lack of parental knowledge of infant immunization timing is associated with delayed immunization coverage. In an effort to improve Latino parent knowledge of immunization timing, two Spanish-language radio commercials were developed to be used in conjunction with community-based educational efforts. In order to gage the potential educational impact of the two commercials, they were pretested with a group of low-income Spanish-speaking Latino parents who represented members of the target population for whom the commercials were created. Both commercials were rated favorably by parents, and elicited immunization-specific responses. Although correct recall of the simplified, basic immunization schedule was low, the level of immunization response consistency and overall approval of both commercials appear to support their use as part of Latino infant immunization educational outreach in California.

Correlations among physical activity and eating behaviors in 4- to 7-year-old Anglo- and Mexican-American children.

Physical activity and dietary behaviors are often correlated in adults and adolescents. This association was examined in 351 Anglo- and Mexican-American children between the ages of 4 and 7 years. Behaviors were assessed by structured observations and interviews at home and school. Observed physical activity was significantly correlated with energy intake (r = .43), but was unrelated to the percentage of calories from total fat or saturated fat. Thus, interventions with young children to improve dietary behavior or physical activity should not be expected to automatically lead to changes in the other.

Determinants of dietary intake in a sample of white and Mexican-American children.

OBJECTIVE: To assess the influence of several potential psychosocial determinants on children's eating behavior. PARTICIPANTS: Three hundred fifty-one Mexican-American and non-Hispanic white children (mean age = 4.4 years old at baseline) participated in the San Diego Study of Children's Activity and Nutrition for up to 2.5 years. METHODS: Child's eating behavior was described by 3 dependent variables: total energy, percentage energy from fat, and sodium intake per 1,000 kcal. Dietary information was collected 4 days a year using a 24-hour food intake record, which was a combination of direct observation and interviews with food preparers. The 35 predictor variables from child, parental, demographic, and environmental domains were collected by behavioral observation, interviewer-administered questionnaires, and physical measurements. STATISTICAL ANALYSES: Bivariate and regression analyses via mixed linear models were performed. RESULTS: Variables from the children's domain (such as skinfold thickness and weight) had the strongest associations with energy intake; parental variables (such as fat avoidance behavior and prompts to increase children's food intake) were associated with child's percentage energy from fat and sodium intake. In regression analyses, parsimonious subsets of variables accounted for 46% of variance in energy intake (3 variables), 40% of the variance in percentage of energy from fat (4 variables), and 44% of variance in sodium intake per 1,000 kcal energy (1 variable) in between-subject variance components. CONCLUSIONS: Fat and sodium intake of children may be improved by improving parents' nutrition habits and by having parents encourage children to eat a healthful diet. Few modifiable correlates of children's energy intake were identified.

Skin cancer prevention counseling by pharmacists: specific outcomes of an intervention trial.

The purpose of this study was to evaluate the effects of an intervention on pharmacists' behaviors, knowledge, and attitudes related to skin cancer prevention counseling. Fifty-four pharmacy sites (N = 178 pharmacists) were randomly assigned to the intervention or control condition. Intervention consisted of video-based training, prompts installed in the pharmacy to promote pharmacist-patient discussions on the topic, and group-based feedback on previous week's counseling rates. Outcomes were measured using a mailed survey. The proportion of patients counseled at post-test was significantly higher among intervention subjects, adjusting for pretest values. Similar results were found for pharmacists' skin cancer knowledge and self-rated expertise, but not for counseling-related attitudes. The intervention was successful. If implemented on a wide scale, large segments of the U.S. population would be exposed to skin cancer prevention advice.

Initial results of 'Language for Health': cardiovascular disease nutrition education for English-as-a-second-language students.

Low literacy skills may negatively affect health through misuse of medication, inability to follow medical directions or due to limitations placed on the consumer's ability to access health information. The association between low literacy among adults and cardiovascular disease has not been thoroughly investigated in some ethnic groups. The purpose of this comprehensive study is to describe the results of a nutritional-related cardiovascular health program for limited English proficient adults enrolled in English-as-a-second-language (ESL) classes. Subjects (n = 408), nearly 87% of whom were Latino, were exposed to either nutrition education (intervention group) or stress management (attention-placebo control group) classes designed specifically for ESL classes. Subjects completed physiological measures assessing blood pressure, total and high-density lipoprotein (HDL) cholesterol, waist and hip circumference, and body mass. Self-report surveys were administered to collect students' nutrition-related knowledge, attitudes and behaviors. Data were collected at baseline, 3 month post-test and 6 month follow-up. Analyses showed that differential group change was seen for fat avoidance, nutrition knowledge, HDL and total cholesterol:HDL ratio, but, for the two latter variables, the effect was not maintained at the 6 month follow-up. Both groups showed positive changes in blood pressure, total cholesterol and nutrition-related attitudes. Results showed moderate success of the intervention, but suggest contamination between experimental groups may have occurred.

Direct home observations of the prompting of physical activity in sedentary and active Mexican- and Anglo-American children.

Social interactions are important correlates of physical activity in children. Previous studies used global measures; the present study examined the influence of specific social interactions on immediate physical activity in children with data obtained from the Behaviors of Eating and Activity for Child Health: Evaluation System (BEACHES). The study examined parental and peer prompting of physical activity at home among 178 Mexican-American and 113 Anglo-American children at age 4 years and again at age 6.5 years. Most activity prompts came from adults interacting with children when they were sedentary. A reduction in the frequency of prompts from baseline to follow-up occurred in the prompter group (adult or child peer), gender, ethnicity, and preprompted activity level categories. Children's responses to these prompts showed that as they aged, they seemed to rely less on the interpersonal (especially adult) aspects of their environment for cues to be more active.
