Dietary factors and cancers of breast, endometrium, and ovary: strategies for modifying fat intake in African American women

The theory of music, mood and movement to improve health outcomes

AIM

This paper presents a discussion of the development of a middle-range nursing theory of the effects of music on physical activity and improved health outcomes.

BACKGROUND

Due to the high rate of physical inactivity and the associated negative health outcomes worldwide, nurses need new evidence-based theories and interventions to increase physical activity.

DATA SOURCES

The theory of music, mood and movement (MMM) was developed from physical activity guidelines and music theory using the principles of statement and theory synthesis. The concepts of music, physical activity and health outcomes were searched using the CINAHL, MEDLINE, ProQuest Nursing and Allied Health Source, PsycINFO and Cochrane Library databases covering the years 1975-2008.

DISCUSSION

The theory of MMM was synthesized by combining the psychological and physiological responses of music to increase physical activity and improve health outcomes. It proposes that music alters mood, is a cue for movement, and makes physical activity more enjoyable leading to improved health outcomes of weight, blood pressure, blood sugar and cardiovascular risk factor management, and improved quality of life.

CONCLUSION

As it was developed from the physical activity guidelines, the middle-range theory is prescriptive, produces testable hypotheses, and can guide nursing research and practice. The middle-range theory needs to be tested to determine its usefulness for nurses to develop physical activity programmes to improve health outcomes across various cultures.

Body mass index and intake of selected foods in African American men

BACKGROUND

There are minimal data on the relationship between dietary consumption of fats, vegetables, and fruits and body mass index (BMI) in African American men.

OBJECTIVE

This study tested the relationships between selected dietary consumption and BMI.

DESIGN

The sample was a community-based cohort of 204 African American Southern men who attended a free prostate cancer educational and screening program. The screening was part of an all-day African American celebration that included a health fair. Diet was assessed with a Brief Dietary Scale for Selected Food Intake and Preparation.

RESULTS

Most of the men were overweight (34%) or obese (47%). The majority of men ate their chicken (90%) and fish (96%) fried. Few men ate vegetables at supper (29.4%) or lunch (15.8%). Three fatty food items were significantly associated with BMI: leaving the chicken skin on chicken (p=.03); intake of low-fat or skim milk (p=.02); and cooking vegetables with butter (p=.03).

CONCLUSION

African American men need culturally appropriate dietary interventions to reduce obesity.

Impact of breast cancer on African American women: priority areas for research in the next decade

Despite all the gains that have been made in the area of breast cancer research, African American women suffer disproportionately from the effects of the disease. Breast cancer is the second leading cause of cancer death among African American women, exceeded only by lung cancer. Improvements in cancer incidence, mortality, and survival rates among populations are undoubtedly the outcome of quality research. Therefore, there is a need to identify and discuss issues regarding breast cancer among African American women and to determine whether these issues should be a part of the nation's breast cancer research agenda. This commentary summarizes the results of the Summit Meeting Evaluating Research on Breast Cancer in African American Women, which was held September 8-11, 2000, in Washington, DC. Listed are priority areas and some of the questions that fueled this 2-day discussion among 130 participants, including health advocates, cancer survivors, and experts representing various areas of cancer research.

Birth characteristics and subsequent risk for breast cancer in very young women

There is growing evidence that prenatal exposures may influence later breast cancer risk. This matched case-control study used linked New York State birth and tumor registry data to examine the association between birth characteristics and breast cancer risk among women aged 14-37 years. Cases were women diagnosed with breast cancer between 1978 and 1995 who were also born in New York after 1957 (n = 484). For each case, selected controls were the next six liveborn females with the same maternal county of residence. The authors found a J-shaped association between birth weight and breast cancer risk, and very high birth weight (> or =4,500 g) was associated with the greatest elevation in risk (adjusted odds ratio (OR) = 3.10, 95% confidence interval (CI): 1.18, 7.97). The association of maternal age with breast cancer risk was also J-shaped, with maternal age of more than 24 years showing a positive, linear association (adjusted OR = 1.94, 95% CI: 1.18, 3.18 for maternal age > or =35 vs. 20-24 years; p for trend = 0.02). In contrast, women born very preterm had a lower risk (adjusted OR = 0.11, 95% CI: 0.02, 0.79 for gestational age <33 vs. > or =37 weeks). These findings support a role for early life factors in the development of breast cancer in very young women.
