Possible explanations for the decline include the observed trends in risk factors such as changes in rates of hypertension, dyslipidemia, and glucose intolerance; lifestyle changes such as improvements in diet and decreases in the levels of cigarette smoking; and better detection and treatment of heart disease. The specific effects of risk factor, lifestyle, or detection and treatment changes on the declining population rates of coronary heart disease morbidity and mortality were unknown in 1990. Secular trend analyses were needed to elucidate the relative contribution of these factors, particularly dietary variables, on population rates of coronary heart disease.\n\nDESIGN NARRATIVE:\n\nMultiple regression was used to assess the effect of dietary variables on changes in serum cholesterol between 1957-1960 and 1966-1969 in a sample of 200 men for whom repeated measurements existed in the Framingham cohort. Analysis of covariance was used to assess influence of dietary intake on differences in serum cholesterol levels between independent samples of men studied in 1957-1960 and 1966-1969 in the Framingham cohort, and independent samples of women studied between 1957-1960 and 1984-1988 in the Framingham cohort and Offspring cohort, and independent samples of men studied between 1966-1969 and 1984-1988 in the Framingham cohort and Offspring cohorts respectively.\n\nThe study completion date listed in this record was obtained from the "End Date" entered in the Protocol Registration and Results System (PRS) record.'}, 'eligibilityModule': {'sex': 'MALE', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'maximumAge': '100 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'No eligibility criteria'}, 'identificationModule': {'nctId': 'NCT00005257', 'briefTitle': 'Diet and Plasma Cholesterol - Secular Trend Analysis', 'organization': {'class': 'NIH', 'fullName': 'National Heart, Lung, and Blood Institute (NHLBI)'}, 'orgStudyIdInfo': {'id': '1139'}, 'secondaryIdInfos': [{'id': 'R01HL043919', 'link': 'https://reporter.nih.gov/quickSearch/R01HL043919', 'type': 'NIH'}]}, 'contactsLocationsModule': {'overallOfficials': [{'name': 'Barbara Posner', 'affiliation': 'Boston University'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'National Heart, Lung, and Blood Institute (NHLBI)', 'class': 'NIH'}}}}
