    ABSTRACT: KEY FINDINGS: Data from the National Health and Nutrition Examination Survey In 2009-2010, about 47% of adults had at least one of three risk factors for cardiovascular disease-uncontrolled high blood pressure, uncontrolled high levels of low-density lipoproteins (LDL) cholesterol, or current smoking. Men were more likely than women to have at least one of the three cardiovascular disease risk factors. From 1999-2000 through 2009-2010, a decrease was observed in the percentage of non-Hispanic white and Mexican-American adults who had at least one of the three risk factors for cardiovascular disease. However, this decrease was not found among non-Hispanic black adults. The prevalence of uncontrolled high blood pressure and of uncontrolled high LDL cholesterol declined between 1999-2000 and 2009-2010, but no significant change occurred in the percentage of adults who smoke cigarettes.

    ABSTRACT: KEY FINDINGS: Data from the National Health and Nutrition Examination Survey, 2009-2010 Approximately one in four children aged 3-5 and 6-9 years living in poverty had untreated dental caries. Dental sealants were more prevalent among non-Hispanic white adolescents (56%) compared with non-Hispanic black adolescents (32%) aged 13-15. Among adults aged 45-64, 29% had a full set of permanent teeth (excluding third molars); this includes 19% of Hispanic adults and 11% of non-Hispanic black adults compared with nearly 35% of non-Hispanic white adults. More than one-third of older adults aged 65-74 living below the federal poverty level (34%) were edentulous, whereas approximately one-eighth of older adults living above the poverty level (13%) were edentulous.

    ABSTRACT: KEY FINDINGS: Data from the National Health and Nutrition Examination Survey, 2005-2008 More than one in five people had untreated dental caries and 75% had existing dental restorations. Prevalence of untreated dental caries varied significantly by poverty level for all age groups; however, there was little difference in dental restoration prevalence by poverty level for children and adolescents aged 5-19 years. Twenty-seven percent of children and adolescents aged 5-19 years had at least one dental sealant. Nearly 38% of non-Hispanic black adults had not lost a permanent tooth compared with 51% for non-Hispanic white and 52% for Mexican-American persons. Almost 23% of adults aged 65 and over were edentulous.

    ABSTRACT: Los Angeles County has the largest population of any county in the nation. Population-based estimates of health conditions for Los Angeles County are based primarily on telephone surveys, which are known to underestimate conditions of public health importance. This report presents the prevalence of selected health conditions for civilian noninstitutionalized adults aged 20 and over living in Los Angeles County households and group quarters, based on survey data using direct physical measurements. Combined data from the 1999-2000, 2001-2002, and 2003-2004 National Health and Nutrition Examination Surveys (NHANES), conducted by the Centers for Disease Control and Prevention's National Center for Health Statistics, were used for this report. Sample weights were recalculated for participants examined in Los Angeles County using population totals provided by the Los Angeles County Department of Public Health, excluding the institutionalized population. Compared with the nation as a whole, adults in Los Angeles County had similar rates of health conditions even after age and age-race adjustment, with a few exceptions. A significantly smaller proportion of Los Angeles County adults were obese (age-adjusted rate, 23.8%) compared with the United States (31.0%); this difference held after age-race adjustment. The age-adjusted rate of diagnosed diabetes for men was higher in Los Angeles County (9.1%) than in the nation (7.3%); however, this difference did not hold after age-race adjustment. The rates of total diabetes adjusted for age and age-race were similar for men in Los Angeles County and the United States. The rates of selected health conditions in this report were similar for adults in Los Angeles County compared with adults in the United States, with the exception of obesity. The rates of obesity adjusted for age and age-race were lower among Los Angeles County adults compared with national rates. Health estimates based on direct physical measurements can be useful for local public health programs and prevention efforts.
