Adiponectin responses to continuous and progressively intense intermittent exercise.

PURPOSE: Adiponectin is a recently discovered adipocyte protein that is lower in patients with coronary artery disease and in Type II diabetics who have insulin resistance. Regular exercise is known to be a preventative factor in the development of atherosclerosis and Type II diabetes. Acute exercise increases insulin sensitivity; however, it also increases beta-adrenergic and glucocorticoid activities that may suppress adiponectin expression. Two experiments were conducted to determine whether acute exercise affects adiponectin concentrations. METHODS: In the first experiment, six healthy male subjects completed 30 min of heavy continuous running exercise at 79% of VO (2max). In the second experiment, well-trained runners completed strenuous intermittent exercise consisting of treadmill running at 60, 75, 90, and 100% VO (2max). A resting control trial for the second experiment was also conducted. RESULTS: Glucose and insulin were not altered significantly in the first experiment, but both increased significantly (P < 0.05) in the second experiment. A significant increase (P < 0.05) in adiponectin in the first experiment was no longer significant after correction for plasma volumes shifts. In the second experiment, there were significant (P < 0.05) changes in adiponectin concentrations over time but not a significant difference between adiponectin responses in exercise and control trials. CONCLUSIONS: The data suggest that 30 min of heavy continuous running or more strenuous intermittent running does not stimulate an increase in production and release of adiponectin, and small increases in adiponectin concentrations resulting from the exercise may be attributed to normal plasma volume shifts.

Depressive symptoms in farm women: effects of health status and farming lifestyle characteristics, behaviors, and beliefs.

A multitude of responsibilities, environmental and social influences, and stressors place farm women at high risk for depressive symptoms. This cross sectional survey design study examines demographic, health status, and farm lifestyle characteristics, behaviors and beliefs as risk factors contributing to depressive symptoms among farm women in southeast Louisiana. The study was conducted in a stratified, random sample of 657 women 18 years and older. Factors predictive of depressive symptoms in adjusted logistic regression included those who experience poor health, perceive hazards associated with farming, experience recent farm-related injuries and engage in farming over longer periods of time. These findings help target interventions toward women at risk for depressive symptoms.

Nonfatal injury experiences among women on family farms.

Agricultural injury occurrence was determined among 1,096 working farm women in Texas and Louisiana. The 1-year cumulative incidence was 4.8%. Lower extremities were the body parts most frequently injured. The leading external causes were contact with foreign object, followed by falls and overdoing/ lifting. The seasonal pattern of injury was consistent with warm weather. The factors predictive of increased injury risk in multiple logistic regression included large animal farm type, greater time commitment, recurrent or persistent back conditions or weakness during the previous 12 months, hauling goods to market, and driving a tractor more than 52 days per year. Most women consulted a physician as a result of the injury. Resolving the problem of preventable farm-related injuries will require a major and coordinated effort aimed not only at farm women themselves but also at multiple variables that profoundly affect the underlying conditions and behaviors that lead to farm-related injuries.

Occupational risky business: injury prevention behaviors of farm women and children.

On farms in the United States, there are approximately 100 fatal and 32,800 nonfatal injuries annually in children 19 years and younger (United States Department of Labor, 1999). Up to 40% of nonfatally injured children are left with permanent disabilities. The impact of injury and death on children associated with farming in the United States is substantial. Research suggests that modeling of health behaviors may be an effective technique for the socialization of children's health behaviors. The purpose of this study is twofold. First, the study describes the participation and use of protective farm equipment or practices by the caregiver and the child. The second purpose is to compare the practices of the caregivers and the children in relation to the use of protective farm equipment and practices. Descriptive and categorical data analysis methods were used to examine the associations of 177 pairs of caregivers and children and their use of protective equipment and preventative behaviors. Greater than 50% of the children under the age of 7 had handled or touched livestock, as well as rode as passengers on tractors. Many children in all age categories had ridden in the back of pick-up trucks. Modeling of the prevention behavior by the caregivers did parallel the use of the equipment by the children. However, the opposite also was true; if the caregiver did not use the equipment, neither did the child.

The impact of farm lifestyle and health characteristics: cervical cancer screening among southern farmwomen.

BACKGROUND: Rural residence, access to healthcare facilities, and multiple roles of farmwomen may pose barriers to cervical cancer screening among women living in southern farm states. OBJECTIVES: To compare the proportion of women failing to obtain cervical cancer screening in three Southern states to state-level Behavioral Risk Factor Surveillance System (BRFSS) data and to identify factors contributing to cervical cancer screening and detection behaviors. METHODS: A cross-sectional study design was used. Data were collected using several Farm Family Health and Injury Prevention surveys via telephone interviews in three southern states. Farmwomen (N = 2,324) from three states comprised the sample on Pap testing. Data were used from summary reports of the BRFSS for each state to compare the proportion of farmwomen >or=18 years of age who had failed to obtain a Pap test within the past 3 years to failure to obtain Pap tests statewide. Multiple logistic regression analyses were conducted to examine the predictors of failure to obtain early screening. RESULTS: Pap testing did not meet Healthy People 2010 target goal of 90%. Farm lifestyle predicting failure to obtain cervical cancer screening included having a house on the farm and engaging in no off-farm work and minimal involvement in farm tasks. The risk of failing to obtain Pap testing increased with age and decreased with education. The only health access variable contributing to failure to obtain Pap testing was women with no insurance. Positive preventive risk factors contributing to compliance with up-to-date status were previous mammogram and previous breast exam. Being married was a positive risk factor. DISCUSSION: Although the failure to obtain Pap testing in Texas was comparable to state BRFSS rates, failure to obtain Pap testing rates in Kentucky and Louisiana were at least 6% greater for farmwomen than women living in the state. Farmwomen, a subgroup of the rural population, have unique barriers to obtaining screening services. Geographical isolation and minimal role involvement on the farm may contribute to the likelihood that women are not seeking cervical cancer screening.
