By using the theories of help-seeking behavior and health-information seeking, this article demonstrates the relationship between chronic illness, retrieving health information from the Internet and changing health behavior. Research on the impact of health information on the Internet and changing health behavior is fairly new, given the growth of the Internet in recent years. Using US data on Internet use within the US population, multiple regression analysis was performed to explore the relationships between chronic medical conditions and frequency of Internet use, as well as changes in health behavior due to frequency of Internet use. The findings suggest that it is not merely the presence of a particular chronic illness, but rather the total number of chronic conditions that determine Internet use. Also, the more frequently a person uses the Internet as a source of health information, the more likely they are to change their health behavior.
The associations of self-reported measures of physical activity from a mail survey with an objective measure of physical fitness were investigated. Respondents to a health status survey (n = 12,225), conducted in 1982 by the Institute for Aerobics Research in Dallas, TX, formed the population. From this group, males who also had a clinical examination within 60 days of the return of their questionnaire served as subjects. The study subjects (n = 375, mean age = 47.1 years) completed a maximal physical fitness assessment using a modified Balke protocol. The questionnaire included a section of inquiries concerning leisure time physical activity participation in which subjects were asked to quantitatively recall exercise participation for varying periods of time. Reported exercise participation values were converted to estimates of energy expenditure and combined into overall indices of physical activity participation. Multiple regression analyses were used to determine the individual contributions of the physical activity indices in predicting maximal treadmill performance (physical fitness). Significant predictors of physical fitness were age (beta = -0.34), an index of running, walking, and jogging participation (beta = 0.31), and the response to a question on frequency of sweating (beta = 0.35). The multiple correlation coefficient for these variables in predicting physical fitness was 0.65. These results indicate that exercise behavior can be accurately estimated in large populations by using simple questions in a mail survey.
Abstract:The influx of Latino laborers into the U.S. and the confluence of migration-driven factors in an environment ripe for risk-taking have the potential to exacerbate already rising STI/HIV rates among migrants and their social networks at both the home and receiving regions. This paper focuses on Mexican migrant laborers who are among the most marginalized and exploited Latinos in the U.S. This study used ethnographic methods to delineate the sociocultural and spatial contexts and social organization of migrant farmwork, and examined how intertwined individual and environmental factors render migrant farmworkers vulnerable to STI/HIV risks. Findings indicate the presence of a number of factors in the study population of Mexican migrant workers (N = 23)-such as poverty, limited education, physical/social/cultural isolation, long work hours, constant mobility, hazardous work conditions, limited access to health care, low rates of condom use, multipartnering, and use of sexworkers-which increase their risks for STI/HIV transmission. To be successful, prevention efforts need to focus not only on condom education and HIV awareness and testing, but also on reducing migrants' social isolation and understanding their social networks.
The reliability of long-term recall of physical activity participation was examined in 322 women and 129 men in a worksite health study conducted at the Liberty Corporation, Greenville, South Carolina during 1976-1987. Leisure time physical activity was assessed at baseline; and energy expenditure in total, light, moderate, and vigorous activities was calculated. The long-term recall of baseline activities was determined 1-10 years after the examination. The relation between actual baseline and recalled activity was positive and in most cases the coefficients were statistically significant at p less than 0.05. The correlations were modest, most in the range of 0.20 to 0.50. Percent agreement between baseline and recalled activity generally ranged from 60 to 75%. Multiple regression analyses suggested that recalled activity was a significant predictor of baseline activity, but recall interval and age were not important contributors to the regression model. R2 values for the model were 0.10 for light activity and 0.26 for vigorous activity. Questionnaire assessment of long-term physical activity recall appeared to be reliable, length of recall interval up to 10 years was not an important factor, and recall of vigorous activity was more accurate than for less intensive activities.
These data support a protective effect of physical fitness and physical activity on functional limitation among older adults and extend this protective effect to middle-aged men and women.
We found that children of less educated mothers and children in Hispanic and non-Hispanic Black families with low income-to-poverty ratios were more likely to have completed the 4:3:1:3 series. Although the reasons for these results need further exploration in other data sets, possible factors are Hispanics' positive cultural attitudes regarding the needs and importance of young children and provision of information on immunizations to low-income minority mothers who access government-subsidized health care programs.
This article assesses the relationship between parents' perceived risk of childhood injuries and familial, sociocultural, and situational variables. Data were obtained through a random digit dial telephone survey of 1,200 households with a preschool child in a southeastern metropolitan area. Perceived risks of childhood injury measures were based on social science theory and childhood injury epidemiology. Multiple item measures included dimensions of seriousness and likelihood for both injuries and hazards. When risk perceptions were viewed as individual items, parents underestimated the risk of some hazards and injuries and overestimated the risks of others, and parents whose children have sustained a recent injury had higher risk perception overall. When risk perceptions were viewed as summed scales, sociodemographic variables and parental safety behaviors were not significant predictors. Sociocultural factors of having a child previously injured, the parent reporting stress, having a household with self-reported risk factors, and the perception of the child as active and hard to manage are related to summed scales of risk perceptions, with some interactions by race of the parent. Findings illustrate the role of situational and sociocultural characteristics of respondents in risk perception research.
