Sociocultural perspectives on physical activity in the lives of older African American and American Indian women: a cross cultural activity participation study

Cardiovascular Health among U.S. Indigenous Peoples: A Holistic and Sex-Specific Systematic Review

PURPOSE

The purpose of this systematic review is to examine mental, sociocultural, behavioral, and physical risk and protective factors related to cardiovascular disease (CVD) and related outcomes among U.S. Indigenous peoples.

METHODS

A total of 51 articles met the inclusion criteria of research focusing factors for CVD among U.S. Indigenous peoples (Mental n= 15; Sociocultural, n =17; Behavioral/Physical, n =19).

RESULTS

This review reveals clear risks for CVD, which tended to be elevated for females. Mental health problems (depression, anxiety, PTSD/trauma, alcohol and other drug (AOD) abuse) were clearly associated with CVD, along with enculturation, social support, and the social environment-including discrimination and trauma. Poor diet and obesity, diabetes, hypertension, cholesterol were behavioral or physical factors.

DISCUSSION

Overall, identified research was limited and in beginning stages, lacking more information on etiology of the interconnections across sex and the mental, sociocultural, and behavioral determinants of CVD.

Physical and Mental Health Experiences among African American College Students

Transitioning from home to college life can lead to changes in dietary and physical activity behaviors. Approximately 12% to 50% of college students meet criteria for one or more mental disorders. When compared to others, African Americans typically have poorer health outcomes and experience greater rates of cardiovascular-related diseases and depression. The purpose of this qualitative interpretive meta-synthesis (QIMS) was to understand physical and mental health experiences among African American college students to inform policy, practice, and research. Findings from the QIMS revealed two overarching themes: (1) perceptions of physical health and (2) perceptions of mental health. Each theme included three dimensions. The dimensions of perceptions of physical health include (1) exercising for health benefits, (2) exercising for aesthetics, and (3) nutrition versus healthy eating. The dimensions of perceptions of mental health include (1) stress, (2) confidence, and (3) spirituality. These themes enhance understanding of what African American college students perceive and experience when attempting to engage in overall physical and mental health.

Hair As a Barrier to Physical Activity among African American Women: A Qualitative Exploration

Background

African American (AA) women face unique sociocultural barriers to physical activity (PA) engagement. Such barriers may contribute to their low PA levels and high cardiometabolic disease burden. One particular barrier reported among AA women in recent research is that being physically active can have an undesirable effect on the hairstyles and hair maintenance of many AA women. However, the underlying mechanisms contributing to this barrier have not been fully elucidated. The purpose of this study is to explore hairstyle maintenance as a barrier to PA among AA women and to identify effective strategies to overcome this barrier in the design of a culturally relevant PA intervention.

Methods

A qualitative study design was used. Data were collected from the focus groups comprising 23 sedentary and obese AA women (median age = 38.1 years, median body mass index = 39.8 kg/m²). Content analysis was used to analyze these focus group data.

Results

Three key themes emerged from the qualitative narratives of participants: (1) impact of perspiration on hair and hairstyle maintenance, (2) image and social comparisons, and (3) solutions to overcome hair-related barriers to PA. For impact of perspiration and hairstyle maintenance, participants described how perspiring while engaging in PA negatively impacts many of their hairstyles. Participants further discussed how time and monetary burdens associated with PA-related hairstyle maintenance further contributed to this issue. Findings for the theme of image and social comparison focused on how an AA woman’s hairstyle is an important part of the image and the social comparisons made by non-AAs regarding the hairstyles and maintenance practices of AA women. For solutions to hairstyle maintenance barriers, participant described a variety of potential styling techniques that may help alleviate PA-related maintenance concerns, including braids, locks, and natural hairstyles. However, no styling technique was uniformly endorsed by all study participants.

Conclusion

Findings highlight the significance of hair in the AA community and provide further insight on appropriate intervention design strategies to overcome this sociocultural barrier to PA. Future research is needed to corroborate and further expand on our findings.

Total workload and recovery in relation to worktime reduction: a randomised controlled intervention study with time-use data

Objectives

A 25% reduction of weekly work hours for full-time employees has been shown to improve sleep and alertness and reduce stress during both workdays and days off. The aim of the present study was to investigate how employees use their time during such an intervention: does total workload (paid and non-paid work) decrease, and recovery time increase, when work hours are reduced?

Methods

Full-time employees within the public sector (n=636; 75% women) were randomised into intervention group and control group. The intervention group (n=370) reduced worktime to 75% with preserved salary during 18 months. Data were collected at baseline, after 9 months and 18 months. Time-use was reported every half-hour daily between 06:00 and 01:00 during 1 week at each data collection. Data were analysed with multilevel mixed modelling.

Results

Compared with the control group, the intervention group increased the time spent on domestic work and relaxing hobby activities during workdays when worktime was reduced (P≤0.001). On days off, more time was spent in free-time activities (P=0.003). Total workload decreased (−65 min) and time spent in recovery activities increased on workdays (+53 min). The pattern of findings was similar in subgroups defined by gender, family status and job situation.

Conclusions

A worktime reduction of 25% for full-time workers resulted in decreased total workload and an increase of time spent in recovery activities, which is in line with the suggestion that worktime reduction may be beneficial for long-term health and stress.

Stress, Burnout and Coping: Differences between Women with Coronary Heart Disease and Healthy Matched Women

Stress is becoming more significant for women, along with the increasing number of women in the workforce. The present study compared women with respect to burnout and coping abilities, and related to the impact of educational level on differences in coping strategies. Women with coronary heart disease reported a higher level of burnout and had the highest scores demonstrating lack of coping, which indicates lesser coping abilities. Differences concerning strain reduction, self-control and emotional distancing are discussed in terms of living conditions. We also discuss that in order to optimize the outcome of rehabilitation and prevention we need more research on women, of women and especially from women’s point of view.

The Life History Interview Method: Applications to Intervention Development

There is an urgent need to develop and test health promotion strategies that both address health disparities and elucidate the full impact of social, cultural, economic, institutional, and political elements on people's lives. Qualitative research methods, such as life history interviewing, are well suited to exploring these factors. Qualitative methods are also helpful for preparing field staff to implement a social contextual approach to health pro-motion. This article reports results and application of findings of life history interviews conducted as part of intervention planning for the Harvard Cancer Prevention Program Project, “Cancer Prevention in Working-Class, Multi-Ethnic Populations.” The salient themes that emerged from interviews with a multi-ethnic, purposive sample are centered on six construct domains: immigration and social status, social support, stress, food, physical activity, and occupational health. Insights gained from thematic analysis of the interviews were integrated throughout intervention and materials development processes.

Designing Culturally Relevant Physical Activity Programs for African-American Women: A Framework for Intervention Development

BACKGROUND

African-American women perform low levels of physical activity and are disproportionally burdened by associated cardiometabolic disease conditions (i.e., 57 % are obese, 49 % have cardiovascular disease). The marked health disparities among African-American women indicate the need for innovative strategies to promote physical activity to help attenuate the chronic disease health disparities in this high-risk population. Culturally tailoring physical activity programs to address the sociocultural norms, values, beliefs, and behaviors of African-American women is an advantageous strategy to enhance physical activity promotion efforts. The purpose of this article is to discuss critical aspects for researchers to consider when designing physical activity programs for African-American women and to present a conceptual framework to guide intervention development.

METHODS

Development of the framework was based on our previous physical activity research with African-American women, seminal literature on the topics of cultural adaptation and health promotion, sociological and theoretical perspectives on the role of women in African-American culture, and key determinants of physical activity engagement among African-American women.

RESULTS

Three key concepts are discussed in the conceptual framework: (1) Developmental milestones and life stage transitions of African-American women; (2) Historical, social, and cultural influences associated with physical activity engagement; and (3) Intervention delivery strategies.

DISCUSSION

Using the framework to guide intervention development has the potential to enhance the physical activity and health outcomes of a physical activity program for African-American women.

Barriers to Physical Activity Among African American Women: An Integrative Review of the Literature

A key aspect for researchers to consider when developing culturally appropriate physical activity (PA) interventions for African American (AA) women are the specific barriers AA women face that limit their participation in PA. Identification and critical examination of these barriers is the first step in developing comprehensive culturally relevant approaches to promote PA and help resolve PA-related health disparities in this underserved population. We conducted a systematic integrative literature review to identify barriers to PA among AA women. Five electronic databases were searched, and forty-two studies (twenty-seven qualitative, fourteen quantitative, one mixed method) published since 1990 (range 1998-2013) in English language journals met inclusion criteria for review. Barriers were classified as intrapersonal, interpersonal, or environment/community according to their respective level of influence within our social ecological framework. Intrapersonal barriers included lack of time, knowledge, and motivation; physical appearance concerns; health concerns; monetary cost of exercise facilities; and tiredness/fatigue. Interpersonal barriers included family/caregiving responsibilities; lack of social support; and lack of a PA partner. Environmental barriers included safety concerns; lack of facilities; weather concerns; lack of sidewalks; and lack of physically active AA role models. Results provide key leverage points for researchers to consider when developing culturally relevant PA interventions for AA women.

Relationships Between Body Areas Satisfaction, Exercise, and Mood in Obese African American Women

Despite a rate of morbid obesity that is 2.5 times that of European American women, African American women have higher body areas satisfaction than any other ethnicities. Previous research suggested differences in African American women’s attitudes toward body image may contribute to a lack of motivation to engage in weight management behaviors, such as physical activity. In addition, factors such as self-efficacy, self-regulation, and mood have been shown to affect healthy behavior participation but have not been studied among obese African American women. This study investigated if changes from baseline to posttreatment in self-efficacy and self-regulation for exercise and mood mediatedthe association between changes in body areas satisfaction and physical activity. The study used archival data consisting of 109 obese African American women who participated in a 6-month weight management intervention. The relationship between changes in body areas satisfaction and physical activity was mediated by changes in self-regulation for exercise and mood but not by change in self-efficacy for exercise. These findings may help in devising treatments targeted at this population. Implications are discussed.

Cardiovascular Disease Prevention Preferences of a Sample of Urban American Indians

This study identified program delivery preferences and barriers to physical activity and healthy eating. Ninety-nine urban dwelling American Indians completed a questionnaire at powwows, community events, and a community health center. Most frequently selected program delivery preferences were coaching or other human contact, with fewer willing to use computer or telephone coaching. Fifty-six selected attending 8, 12, or 16 sessions. Most frequently selected barriers to physical activity were lack of time ( n = 48) and pain from existing problems ( n = 33). Frequently identified barriers to eating healthy foods included expense ( n = 42), uncertainty regarding what foods are healthy ( n = 25), extra time needed for preparation ( n = 22), and lack of knowledge of how to prepare healthy food ( n = 22). Findings showed the need for programs to focus on decreasing the barriers of time for physical activity and healthy eating and encourage doing organized physical activity (not necessarily exercise) with others to increase physical activity.

Selected sociocultural correlates of physical activity among African-American adults

OBJECTIVE

Previous studies have identified several factors to be associated with physical activity (PA) among African-Americans, e.g., demographic and health-related characteristics. Formative studies suggest a link between sociocultural factors and PA among ethnic minorities; yet, it is unclear whether these factors play a role in PA among African-Americans. This paper explores the association of selected sociocultural characteristics with self-reported PA by gender among African-American adults, taking into account demographic and health-related characteristics.

DESIGN

Data from the baseline survey of a colorectal cancer communication intervention trial were used. Participants included 446 African-American men and women, aged 45-75 years. Self-report data were collected on demographics, health-related characteristics, selected sociocultural constructs (e.g., ethnic identity, religiosity, collectivism, and medical mistrust), and PA. PA was categorized as meeting or not meeting recommended levels; recommended levels were defined as participating in vigorous PA for 20 minutes/day for at least three days/week or moderate PA for 30 minutes/day for at least five days/week or a minimum of 600 MET-minutes/week in at least five days. Chi-square and multivariate logistic regression models were used to characterize the association between the selected sociocultural constructs and PA among men and women, after adjusting for demographic and health-related characteristics.

RESULTS

Most participants reported some PA but only 59% were found to be meeting recommended levels. Univariate analyses revealed that high collectivist attitudes were associated with meeting recommended PA (OR = 1.74), particularly for women (OR = 1.81). In multivariate analyses, high collectivist attitudes were significantly associated with meeting PA recommendations among men (OR = 1.87); while high religiosity and high collectivism were significant among women (OR = 1.87 and 1.85, respectively).

CONCLUSIONS

Few of the selected sociocultural characteristics were found to be associated with meeting recommended PA levels. Further study is needed to understand the association of these characteristics with PA among African-Americans.

Physical activity in US Blacks: a systematic review and critical examination of self-report instruments

Background

Physical activity self-report instruments in the US have largely been developed for and validated in White samples. Despite calls to validate existing instruments in more diverse samples, relatively few instruments have been validated in US Blacks. Emerging evidence suggests that these instruments may have differential validity in Black populations.

Purpose

This report reviews and evaluates the validity and reliability of self-reported measures of physical activity in Blacks and makes recommendations for future directions.

Methods

A systematic literature review was conducted to identify published reports with construct or criterion validity evaluated in samples that included Blacks. Studies that reported results separately for Blacks were examined.

Results

The review identified 10 instruments validated in nine manuscripts. Criterion validity correlations tended to be low to moderate. No study has compared the validity of multiple instruments in a single sample of Blacks.

Conclusion

There is a need for efforts validating self-report physical activity instruments in Blacks, particularly those evaluating the relative validity of instruments in a single sample.

Low discretionary time as a barrier to physical activity and intervention uptake

OBJECTIVE

To determine whether self-reported discretionary time was associated with physical activity and uptake of a physical activity promotion intervention in a multi-ethnic urban sample.

METHODS

We examined the association of self-reported discretionary time with hours/week of leisure-time physical activity at baseline and physical activity intervention uptake.

RESULTS

Low levels of discretionary time were significantly (P<0.01) associated with fewer hours/week (beta=-0.78, 95%CI=-1.34, -0.22) of physical activity at baseline. Discretionary time was not associated with physical activity intervention uptake.

CONCLUSION

Lack of discretionary time may serve as barrier to physical activity, but its importance on intervention uptake is less clear.

Traditional foods and physical activity patterns and associations with cultural factors in a diverse Alaska Native population

OBJECTIVES

To determine the prevalence of traditional food and physical activity use and associations with cultural factors among 3,830 Alaska Native and American Indian (AN/AI) people enrolled in the Education and Research Towards Health (EARTH) Study in 3 regions of Alaska.

STUDY DESIGN

Cross-sectional analysis of baseline data from a cohort study.

METHODS

Participants (2,323 women and 1,507 men) completed a computer-assisted self-administered questionnaire that included information on diet, physical activity, life-style and cultural factors.

RESULTS

Over 92% of participants reported eating at least 1 traditional food in the past year. The top 3 traditional foods reported were fish, moose and agutaq (a mixture of berries and fat). The percentage of people who consumed traditional foods varied by region and age but not by sex (p < 0.01). Almost 70% of participants engaged in at least one traditional harvesting physical activity. Picking berries or greens, cutting/smoking fish or meat and fishing were the most common activities. Participation in traditional physical activity was highest in south-west Alaska and was higher among men than women, but did not differ by age (p < 0.01). Both traditional food and physical activity were associated with greater tribal self-identification, speaking a Native language at home, using traditional remedies and participating in or attending traditional events (p < 0.05).

CONCLUSIONS

The EARTH Study found relationships between traditional food use, physical activities, cultural activities and behaviours. Consumption of a variety of traditional foods and participation in traditional physical activities remain an important part of the contemporary Alaska Native life-style. Efforts to promote and sustain these foods and activities in AN/AI populations may lead to improved health outcomes.

Psychosocial issues facing African and African American women diagnosed with breast cancer

Breast cancer is a global issue. The World Health Organization estimates that approximately 1.2 million people will receive a diagnosis of breast cancer each year. Breast cancer continues to be the most diagnosed cancer for all women, after skin cancer, both within the United States and worldwide. Although the incidence of breast cancer among African and African American women is lower than that of European and White American women, their mortality rate is significantly higher. Findings indicated the common denominators for African, African American, and Caribbean women regarding breast cancer are that (1) they present at younger ages, (2) they present having advanced-stage tumors, (3) they are often from lower socioeconomic levels, and (4) they lack knowledge regarding causes and treatment of breast cancer. Social workers in their roles as researchers and advocates can identify gaps within the health care system that adversely impact these women. As policy makers and educators, social workers can design interventions to ensure that the needs of these women and their support system are fulfilled.

An Overview and Proposed Framework of Social-Environmental Influences on the Physical-Activity Behavior of Women

Objective.

The primary purposes of this review were to identify key social-environmental influences on the physical-activity behavior of women and to propose an organizing framework of these influences in the social environment.

Data Sources.

Computerized searches of MEDLINE, Science Direct, and CINAHL were conducted to identify relevant research.

Study Inclusion and Exclusion Criteria.

Studies were included if they used a sample of adult women or included gender-specific analysis, identified or measured some aspect of the social environment in relation to physical activity, and were published in English within the last two decades.

Data Extraction.

Characteristics of study design, sample population, and identified social-environmental variables were extracted.

Data Synthesis.

Through an iterative review of the data by several researchers, common influences and themes were identified and organized into a social environment framework, which included the following components: social support/social networks, life transitions/multiple roles, and cultural standards/gender role expectations.

Results.

Women are exposed to societal messages that indicate physical activity is not a priority and may be inappropriate; they may also lack the social support necessary to adopt and maintain physical activity.

Conclusions.

This review reveals the complex range of factors in the social environment that influence women, and it provides support for the importance of the social environment on physical-activity behavior in women. A social-environmental framework related to Bronfenbrenner's social ecological model is proposed along with recommended strategies to apply in interventions targeting women.

Relationship of health behavior theories with self-efficacy among insufficiently active hypertensive African-American women

OBJECTIVE

While self-efficacy plays an important role in physical activity, relatively little research has examined this construct in minorities. This study identified theoretical correlates associated with self-efficacy among insufficiently active, hypertensive Black women.

METHODS

Correlates of self-efficacy to: (1) overcoming barriers to physical activity; (2) making time for activity; and (3) "sticking with" physical activity were studied.

RESULTS

Sixty-one women (M=50.48+/-4.2 years) participated. We accounted for 32% of the variance in confidence in overcoming barriers. Women confident in overcoming barriers reported less worry about physical activity. The TTM processes of change were also in the model: consciousness raising, environmental reevaluation, counter conditioning, and self-liberation. We accounted for 16% of the variance in "making time" self-efficacy. An aversiveness barrier (e.g., physical activity is boring, physical activity is hard work) was the dominant variable in the model. Confidence to 'stick with' physical activity was associated with self-reevaluation (i.e., reflection on how personal values correspond to behavior). Social support and competing demands were not associated with self-efficacy.

CONCLUSIONS

Consistent with Social Cognitive Theory, results suggest that self-efficacy is behavior specific and each measure likely provides unique information.

PRACTICE IMPLICATIONS

Interventions should be tailored to address specific self-efficacy types.

Self-reported physical activity among blacks: estimates from national surveys

BACKGROUND

National surveillance data provide population-level estimates of physical activity participation, but generally do not include detailed subgroup analyses, which could provide a better understanding of physical activity among subgroups. This paper presents a descriptive analysis of self-reported regular physical activity among black adults using data from the 2003 Behavioral Risk Factor Surveillance System (n=19,189), the 2004 National Health Interview Survey (n=4263), and the 1999-2004 National Health and Nutrition Examination Survey (n=3407).

METHODS

Analyses were conducted between January and March 2006. Datasets were analyzed separately to estimate the proportion of black adults meeting national physical activity recommendations overall and stratified by gender and other demographic subgroups.

RESULTS

The proportion of black adults reporting regular PA ranged from 24% to 36%. Regular physical activity was highest among men; younger age groups; highest education and income groups; those who were employed and married; overweight, but not obese, men; and normal-weight women. This pattern was consistent across surveys.

CONCLUSIONS

The observed physical activity patterns were consistent with national trends. The data suggest that older black adults and those with low education and income levels are at greatest risk for inactive lifestyles and may require additional attention in efforts to increase physical activity in black adults. The variability across datasets reinforces the need for objective measures in national surveys.

Attitudes and perceptions of AIDS clinical trials group site coordinators on HIV clinical trial recruitment and retention: a descriptive study

HIV-seropositive blacks, Hispanics, women of all ethnicities, and injection drug users (IDUs) have low rates of clinical trial participation. The opinions of research nurses and study coordinators as potential facilitators and barriers to access to clinical trials may contribute to this disparity. Study coordinators and research nurses from the adult AIDS Clinical Trials Group (ACTG) clinical trials units responded to an anonymous computer-based survey comprising multiple choice questions and clinical scenarios. Descriptive statistics were used to determine frequencies of responses. Recruitment rates of blacks, Hispanics, women and IDUs were mostly rated appropriate compared with the geographic region demographics. Most sites ranked white men as being the most interested in clinical trials. Sites rated their most effective interactions were with white men. Respondents felt they were less likely to enroll individuals who had missed previous clinical appointments or did not speak English. Perceptions that IDUs, Hispanics, blacks, and, to a lesser extent, women had less interest in clinical trials participation than white males may affect recruitment of the targeted populations. Interventions to improve interactions with targeted populations and to remove logistical and language barriers may improve the diversity of clinical trial participants.

Developing Long-Term Physical Activity Participation: A Grounded Theory Study With African American Women

Regular physical activity is linked to a reduced risk of obesity and chronic disease. African American women bear a disproportionate burden from these conditions and many do not get the recommended amount of physical activity. Long-term success of interventions to initiate and maintain a physically active lifestyle among African American women has not been realized. By clearly elucidating the process of physical activity adoption and maintenance, effective programming could be implemented to reduce African American women's burden from chronic conditions. In-depth interviews were conducted with physically active African American women. Grounded theory, a rigorous qualitative research method used to develop theoretical explanation of human behavior grounded in data collected from those exhibiting that behavior, was used to guide the data collection and analysis process. Data derived inductively from the interviews and focus groups guided the development of a behavioral framework explaining the process of physical activity evolution.

Correlates of Self-Efficacy for Physical Activity in African American Women

This study examined the correlates of self-efficacy for physical activity in African American women. In bivariate analyses, self-efficacy was higher among women reporting fewer social role constraints, more positive perceptions of physically active women, more positive sense of community, better perceived health, and higher levels of physical activity. In a simultaneous multivariate model, more positive perceived health status (p = .001), higher physical activity level (p = .007), and lower social role constraint (p = .02) were independently associated with higher self-efficacy. Thus, physical activity interventions for African-American women should include strategies to decrease social role constraint and offer safe activities for women with health conditions hindering physical activity.

Engendering health disparities

How is gender implicated in our exploration of health disparities in Canada? Set against the backdrop of federal government policy, this review paper examines the ways in which gender intersects with other health determinants to produce disparate health outcomes. An overview of salient issues including the impact of gender roles, environmental exposures, gender violence, workplace hazards, economic disparities, the costs of poverty, social marginalization and racism, aging, health conditions, interactions with health services, and health behaviours are considered. This review suggests health is detrimentally affected by gender roles and statuses as they intersect with economic disparities, cultural, sexual, physical and historical marginalization as well as the strains of domestic and paid labour. These conditions result in an unfair health burden borne in particular by women whose access to health determinants is--in various degrees--limited. While progress has certainly been made on some fronts, the persistence of health disparities among diverse populations of women and men suggests a postponement of the vision of a just society with health for all that was articulated in the Federal Plan on Gender Equality. Commitment, creativity and collaboration from stakeholders ranging from various levels of government, communities, academics, non-governmental agencies and health professionals will be required to reduce and eliminate health disparities between and among all members of our society.

Cardiovascular health among Asian Indians (CHAI): a community research project

The object of this research was to assess cardiovascular (CV) risks in Asian Indians in California. We conducted eight focus groups and a pilot survey using community-based participatory research (CBPR) methods. Focus groups were held in six communities. Surveys were conducted by telephone or in person in areas selected for high population densities of Asian Indians. We selected focus group subjects by snowball sampling (n = 57). We held six English and two Punjabi groups. We used a surname-based phone list from three area codes for telephone interviews (n = 254). We added 50 in-person interviews for comparison (total n = 304) and did 50 interviews in Punjabi. We held community meetings for dissemination. Focus groups discussed CV risks; themes developed aided survey development. In-person and telephone surveys were feasible. Telephone surveys were more gender-balanced and people more often answered alcohol, tobacco, and income questions. Self-reported prevalences for hypertension, hypercholesterolemia, and diabetes were 20.4, 35.3 and 10.6%, respectively. Only 11.9% of persons reported ever smoking cigarettes. It was concluded that CBPR methods were effective in this exploratory study assessing CV risks in Asian Indians. Hypertension, high cholesterol, and diabetes were more prevalent in participants than the population average; other risk factors were less common (tobacco).

Struggle as the Context of Household Health Work for Mexican American Women

A focused ethnographic study was conducted among 13 moderately to highly acculturated American mothers of Mexican ancestry to determine how they influence the health of their family members. Using the World Health Organization (WHO) definition of health (a state of physical, mental, and social well-being and not merely the absence of disease) as a guide for interview questions, we conducted 32 in-depth interviews with study participants. The thread of struggle ran through each woman's narrative. Women's process of struggle is presented as one way to conceptualize the gendered nature of household health work.

Occupational cancer among women: where have we been and where are we going?

Studies of occupational exposures have been a fruitful area of research for identifying carcinogens. Some of the early observations, such as increased risk of breast cancer among nuns and bone cancer among radium dial workers, were made among women. Recent research on cancer among women has shown increased risks of cancer in many industries and occupations. Estimates that 1% of cancer among women is attributable to occupation are based on research conducted mainly in the 1970s among men in developed countries. These studies do not reflect the dramatic changes in the participation of women in the workplace or the patterns of employment of women in developing countries. The proportion of women in the paid workforce, the amounts and types of unpaid labor, the distribution of women by economy sector, the scale of the workplaces, the allowable exposure levels in the workplace, and implementation of controls have changed over time and vary internationally. Occupational cancer researchers need to expand their focus on women, increase activities in developing countries, include newly created industries, use sophisticated exposure assessment methods, and, where appropriate, incorporate molecular epidemiologic techniques to discover new occupational carcinogens and to identify where better control measures are needed.

Model for incorporating social context in health behavior interventions: applications for cancer prevention for working-class, multiethnic populations

BACKGROUND

This article proposes a conceptual framework for addressing social contextual factors in cancer prevention interventions, and describes work that operationalizes this model in interventions for working class, multiethnic populations.

METHODS

The Harvard Cancer Prevention Program Project Includes Three Studies: (1) an intervention study in 25 small businesses; (2) an intervention study in 10 health centers; and (3) a computer simulation modeling project that translates risk factor modifications into gains in life expectancy and number of cancers averted. The conceptual framework guiding this work articulates pathways by which social context may influence health behaviors, and is used to frame the interventions and guide evaluation design.

RESULTS

Social contextual factors cut across multiple levels of influence, and include individual factors (e.g., material circumstances, psychosocial factors), interpersonal factors (e.g., social ties, roles/responsibilities, social norms), organizational factors (e.g., work organization, access to health care), and neighborhood/community factors (e.g., safety, access to grocery stores). Social context is shaped by sociodemographic characteristics (e.g., social class, race/ethnicity, gender, age, language) that impact day-to-day realities.

CONCLUSIONS

By illuminating the pathways by which social contextual factors influence health behaviors, it will be possible to enhance the effectiveness of interventions aimed at reducing social inequalities in risk behaviors.

Antecedents and consequences of work-family conflict: a prospective cohort study

This study examined both risk factors for the onset of work-family conflict and consequences in terms of need for recovery and prolonged fatigue for men and women separately. Two-year follow-up data from the Maastricht Cohort Study on "Fatigue at Work" (n = 12,095) were used. At baseline, the prevalence of work-family conflict was 10.8% (9.0% in women; 11.1% in men), the cumulative incidence at 1 year follow-up was 5.1%. For men, several work-related demands, shift work, job insecurity, conflicts with coworkers or supervisor, having full responsibility for housekeeping, and having to care for a chronically ill child or other family member at home were risk factors for the onset of work-family conflict, whereas decision latitude and coworker and supervisor social support protected against work-family conflict. In women, physical demands, overtime work, commuting time to work, and having dependent children were risk factors for work-family conflict, whereas domestic help protected against work-family conflict at 1 year follow-up. Work-family conflict was further shown to be a strong risk factor for the onset of elevated need for recovery from work and fatigue.

A synthesis of perceptions about physical activity among older African American and American Indian women

OBJECTIVES

In this review of qualitative data from the Cross-Cultural Activity Participation Study (CAPS), we synthesize the major findings of studies designed to identify minority women's perceptions of physical activity.

METHODS

We interviewed 30 African American and 26 American Indian women with constant comparison techniques. We analyzed the data with a coding system developed from the data.

RESULTS

The women led active, busy lives. Most perceived physical activity as being good for them, identified constraints to time and space for physical activity, and wanted social support for physical activity. Sociocultural issues also were related to physical activity.

CONCLUSIONS

Both personal and cultural values influenced the women's physical activity behaviors.

Estimating energy expenditure from the Minnesota Leisure Time Physical Activity and Tecumseh Occupational Activity questionnaires - a doubly labeled water validation

An accurate, simple method for assessing energy expenditure in individuals and in free-living populations continues to be elusive. To compare estimates of energy expenditure (EE) from a combination of two previously validated physical activity questionnaires: Tecumseh Occupational (EE(TEC)) and a 4-wk history version of the Minnesota Leisure Time Physical Activity that included household activities (EE(MNLTPA)) and EE from sleep (EE(SLEEP)), to EE obtained from doubly labeled water (EE(DLW)). We studied free-living males (n = 24) eating a controlled diet designed to maintain body weight and determined EE from doubly labeled water (DLW) during 14 days and EE from physical activity instruments used in epidemiological studies (EE(TEC) and EE(MNLTPA)). There was excellent agreement between EE(DLW) (mean +/- SEM, 13.55 +/- 0.38 MJ/d) and EE(TEC) + EE(MNLTPA) + EE(SLEEP) (EE(TOTAL1)) (13.79 +/- 0.89 MJ/d) with a difference of only 1.0% +/- 5.4%. When the EE from watching TV, reading, and childcare activities was added the total EE (EE(TOTAL2)) (14.87 +/- 0.90 MJ/D) overestimated EE(DLW) by 8.9% +/- 5.4%. Both of these estimates of EE had significant regressions against EE(DLW) (EE(TEC) + EE(MNLTPA) + EE(SLEEP), R(2) = 0.38, P < 0.001; EE(TOTAL2), R(2) = 0.39, P < 0.001). Men whose occupations involved significant intermittent moderate activity had the largest disagreement between EE(DLW) and estimates from the questionnaires. This investigation demonstrates that a combination of previously validated physical activity questionnaires can be used to accurately determine the mean energy expenditure of a population of employed males.

Physical activity among older Filipino-American women

Filipino women (N = 530, mean age 63 years, predominantly low income) were recruited through various community based organizations and churches in Los Angeles County. All women were randomly invited to attend a single group session with a Filipino health educator to discuss breast and cervical cancer screening or the health benefits of exercise. At 3 months after the group session, the exercise assessment tool used in the National Health and Nutrition Examination Survey III was completed by 487 women (92 percent retention rate). This paper describes the pattern of physical activity among older Filipino-American women and a physical activity intervention specifically designed for this group.
