Major Points:

1. Heterogeneity of Blood Pressure Control in Hispanic Population.

2. Lifestyle and Environmental determinants of high blood pressure control among Hispanics.

3. Recommendations to eliminate disparities and improve hypertension control rates.

The Latino Paradox in Los Angeles

Source: Glenn Braunstein, MD Cedars-Sinai Medical Center Accessed at www.Huffingtonpost.com on , Oct 4, 2010

•  Los Angeles is the healthiest it's been since the late 1990s. The county's death rate dropped 22 percent from 1998 to 2007.

•  Latinos had fewer deaths than blacks - despite comparable levels of income and access to health insurance. They also enjoyed lower mortality rates than non-Hispanic whites.

•  Life expectancy among Latinos is 84.4 years - four years longer than the county average.

Disparities, Inequalities or Inequities

•  Health Disparities= as differences in the occurrence, frequency, death, and burden of diseases and other unfavorable health conditions that exist among specific population groups, including racial and ethnic minority groups.

Determinants of Health Disparities •  Natural, biological variation; •  Freely chosen health damaging

behavior; •  Transient health advantage of one over

another (first adopters of health promoting behavior);

•  Health damaging behavior where the degree of lifestyle choices is severely restricted;

•  Exposure to unhealthy, stressful living and working conditions;

•  Inadequate access to essential health and other basic services;

•  Natural selection (health related mobility) Sick people have less social advancement

Definitions

•  Hypertension >=140/90 or currently taking medication to lower high blood pressure

•  Undiagnosed hypertension: A finding of HBP but never told by health care provider that blood pressure was high

•  Treatment: Taking Rx to lower blood pressure •  Controlled: BP<=140/90 •  Treated-uncontrolled: Taking Rx but BP>=140/90 •  Resistant hypertension: failure to achieve goal BP after

full doses of 3-drug regimen, including diuretic •  Pulse Pressure = SBP-DBP

produced unintended consequences that make it difficult for many individuals to maintain a healthy lifestyle

Surgeon General’s Report on Physical Activity and Heath, 1996

•  Major findings: – People who are usually inactive can improve

their health by becoming moderately active on a regular basis

– Physical activity need not be strenuous to achieve health benefits

– Greater health benefits can be achieved by increasing amount (duration, intensity or frequency) of physical activity

Physical Activity is today’s best buy in public health •  Reduces risk of dying prematurely •  Reduces risk of dying from heart disease (and stroke) •  Reduces risk of developing diabetes •  Reduces the risk of developing and lowering high blood

pressure •  Reduces risk of developing certain cancers (colon,

breast) •  Reduces feeling of depression and anxiety •  Helps control weight •  Helps build and maintain healthy bones, muscles and

joints •  Help older adults become stronger and better able to

move about without falling •  Promotes psychological well-being
