RESUMEN
BACKGROUND: African-American women are disproportionately affected by obesity. Weight loss can occur, but maintenance is rare. Little is known about weight loss maintenance in African-American women. OBJECTIVES: (1) To increase understanding of weight loss maintenance in African-American women; (2) to use the elicitation procedure from the theory of planned behavior (TPB) to define the constructs of attitude, subjective norms, and perceived behavioral control regarding weight loss and maintenance; and (3) to help develop a relevant questionnaire that can be used to explore weight loss and maintenance in a large sample of African Americans. DESIGN: Seven focus groups were conducted with African-American women: four with women successful at weight loss maintenance, three with women who lost weight but regained it. Discussions centered on weight loss and maintenance experiences. PARTICIPANTS: Thirty-seven African-American women. APPROACH: Content analysis of focus group transcripts. RESULTS: Weight loss maintainers lost 22% of body weight. They view positive support from others and active opposition to cultural norms as critical for maintenance. They struggle with weight regain, but have strategies in place to lose weight again. Some maintainers struggle with being perceived as sick or too thin at their new weight. Regainers and maintainers struggle with hairstyle management during exercise. The theoretical constructs from TPB were defined and supported by focus group content. CONCLUSIONS: A weight loss questionnaire for African Americans should include questions regarding social support in weight maintenance, the importance of hair management during exercise, the influence of cultural norms on weight and food consumption, and concerns about being perceived as too thin or sick when weight is lost.

BACKGROUND: Cardiovascular disease is the main cause of morbidity and mortality in patients with Marfan syndrome. Many patients with presumed Marfan syndrome do not meet current diagnostic criteria. This study reviews the surgical aspects of aortic disease in 300 patients referred with the diagnosis of Marfan syndrome. METHODS: During a 16-year period, 300 patients with presumed Marfan syndrome underwent 398 operations on the aorta and branch arteries, including 125 aortic root operations, 59 aortic arch repairs, 31 descending thoracic aortic repairs, and 178 thoracoabdominal aortic repairs. Based on medical record review, patients were classified as confirmed Marfan syndrome if documented features satisfied current diagnostic criteria; patients not meeting these criteria were classified as suspected Marfan syndrome. RESULTS: There were 17 operative deaths (4.3%) after the 398 operations. Survival after the initial referral operation was 96.2% +/- 1.5% at 1 year, 82.7% +/- 2.4% at 5 years, and 74.6% +/- 3.1% at 10 years. Presentations, operative details, and outcomes were remarkably similar in the 137 patients (45.7%) with confirmed Marfan syndrome and the 163 patients (54.3%) with suspected Marfan syndrome. Freedom from repair failure, however, was significantly better in patients with confirmed Marfan syndrome (90.3% +/- 2.3% at 10 years) than in those with suspected Marfan syndrome (82.0% +/- 3.1% at 10 years; p = 0.001). CONCLUSIONS: Operative treatment of the full spectrum of aortic disease in Marfan patients enables excellent long-term survival. Similarities in surgical aspects of aortic disease suggest that patients with features of Marfan syndrome who do not meet diagnostic criteria should be managed in the same manner as patients with confirmed Marfan syndrome.
