RESUMO
Storylines of Family Medicine is a 12-part series of thematically linked mini-essays with accompanying illustrations that explore the many dimensions of family medicine, as interpreted by individual family physicians and medical educators in the USA and elsewhere around the world. In 'I: framing family medicine-history, values, and perspectives', the authors address the following themes: 'Notes on Storylines of Family Medicine', 'Family medicine-the generalist specialty', 'Family medicine's achievements-a glass half full assessment', 'Family medicine's next 50 years-toward filling our glasses', 'Four enduring truths of family medicine', 'Names matter', 'Family medicine at its core' and 'The ecology of medical care.' May readers find much food for thought in these essays.

OBJECTIVE: To examine the effect of dietary fiber intake on blood pressure (BP). DESIGN: Randomized, double-blind, placebo-controlled trial. SETTING AND PARTICIPANTS: A total of 110 trial participants aged 30 to 65 years who had untreated, but higher than optimal BP or stage-1 hypertension were recruited from the community in New Orleans, Louisiana, USA. INTERVENTIONS: Study participants were randomly assigned to receive 8 g/day of water-soluble fiber from oat bran or a control intervention. MAIN OUTCOME MEASURES: Nine BP measurements were obtained by trained observers using random-zero sphygmomanometers, over three clinical visits, at the baseline and termination visits of the trial. An average of the nine measurements was used to determine mean BP at the baseline and termination visits. RESULTS: The net changes [95% confidence interval, (CI)] in systolic blood pressure were -1.8 mmHg (-4.3 to 0.8, P = 0.17) following 12 weeks, -2.2 mmHg (-5.3 to 1.0, P = 0.18) following 6 weeks, and -2.0 mmHg (-4.4 to 0.3, P = 0.09) for an average of the 6- and 12-week visits. The corresponding net changes (95% CI) in diastolic blood pressure were -1.2 mmHg (-3.0 to 0.5, P = 0.17) following 12 weeks, -0.8 mmHg (-3.1 to 1.4, P = 0.47) following 6 weeks, and -1.0 mmHg (-2.6 to 0.5, P = 0.19) for an average of the 6- and 12-week visits. CONCLUSIONS: Our findings suggest that a diet rich in fiber may have a moderate BP-lowering effect and indicate the need for further investigation of this important question.

BACKGROUND: Uncontrolled hypertension is the most common and important risk factor for cardiovascular and renal disease. We studied factors associated with hypertension control in the Third National Health and Nutrition Examination Survey. METHODS: A total of 3077 non-Hispanic whites, 1742 non-Hispanic blacks, and 1067 Mexican Americans 18 years or older with hypertension were included in the current analysis. Blood pressure was measured by trained observers by means of a standard mercury sphygmomanometer, and controlled hypertension was defined as a mean systolic/diastolic blood pressure less than 140/90 mm Hg. RESULTS: Percentages of persons with controlled hypertension differed significantly by ethnicity and sex: 19.2% and 28.7% for white men and women, 17.5% and 28.6% for black men and women, and 12.7% and 18.0% for Mexican American men and women, respectively. After adjustment for important covariables, percentages of persons with controlled hypertension were significantly higher among persons who were currently (odds ratio [OR] 2.39; 95% confidence interval [CI], 1.52-3.74) or formerly (OR, 1.81; 95% CI, 1.12-2.93) married, had private health insurance (OR, 1.59; 95% CI, 1.02-2.49), visited the same facility for their health care (OR, 2.77; 95% CI, 1.88-4.09) or saw the same provider for their health care (OR, 2.29; 95% CI, 1.74-3.02), had their blood pressure checked during the preceding 6 months (OR, 8.00; 95% CI, 3.75-17.1) or 6 to 11 months (OR, 5.31; 2.51-11.2), and reported using lifestyle modification to control their hypertension (OR, 6.02; 95% CI, 4.20-8.63). CONCLUSION: These data strongly suggest that access to a regular source of health care and modification of lifestyle are important factors in the control of hypertension in the community.
