MARITAL STATUS AND CARDIOVASCULAR RISK (SERUM, CHOLESTEROL, CIGARETTE, SMOKING, BLOOD, PRESSURE, SYSTOLIC)

There were three purposes of this study. The first was to describe the association between stable marital status and serum cholesterol, systolic blood pressure and cigarette smoking. The second purpose was to determine whether individuals who were married at one point and became widowed or divorced/separated had higher serum cholesterol, higher systolic blood pressure or were more likely to smoke prior to the change in marital status compared with individuals who did not change marital status. The third purpose was to determine whether the changes in marital status described above were related to increases in serum cholesterol or in cigarette smoking behavior. The rationale for the study was to determine whether previously reported associations between marital status categories and cardiovascular mortality may be mediated through higher values of risk correlates for cardiovascular disease among unmarried individuals.^ The study group selected for this dissertation was a sample from the Hypertension Detection and Follow-up Program (HDFP) population. The HDFP population was aged 30-69 years at the initial visit and included blacks and whites, males and females. The population was followed five years after the initial visit and periodic measurements of serum cholesterol, blood pressure and cigarette smoking behavior were obtained.^ Serum cholesterol was not associated with stable marital status category or with marital status prior to change. Changes in serum cholesterol were associated with marital status categories after change but the serum cholesterol values deceased rather than increased. Married individuals were shown to have higher serum cholesterol values compared with unmarried. Selection of the HDFP population may have influenced an ability to detect a significant association between marital status and serum cholesterol but it is doubtful that use of a general population would alter the direction of the association.^ Systolic blood pressure was significantly higher at the initial visit among unmarried white males and females compared with their married counterparts. No association between systolic blood pressure was found among black males or females. Those individuals who were married at the initial visit who experienced a change in marital status were found to have higher systolic blood pressure prior to the change in marital status. . . .

DIABETIC RETINOPATHY IN NON-INSULIN-DEPENDENT DIABETES MELLITUS IN BLACK WOMEN: A DESCRIPTIVE STUDY OF RISK FACTORS

This cross-sectional study examines the prevalence of selected potential risk factors by stage of diabetic retinopathy (DR) among Black American women with non-insulin-dependent diabetes mellitus (NIDDM) followed at a university diabetes clinic. DR was assessed by ophthalmoscopy and five-field retinography, and graded on counts of microaneurysms, hemorrhages and/or exudates, and presence of proliferative DR. Prevalence of other vascular diseases was assessed from medical records. Potential risk factors included age, known duration of diabetes, type of hypoglycemic treatment, concentrations of random capillary blood glucose, glycosylated hemoglobin, urine protein and fibrinogen, body mass index, and blood pressure. Prevalence of these risk factors is reported for three categories: No DR, mild background DR, severe background or proliferative DR (including surgically treated DR). Duration, age at diagnosis and treatment of diabetes, concentration of urine protein and average blood glucose, hypertension and cardiovascular disease were significantly associated with DR in univariate analysis. The covariance analysis employed stratification on duration, age at diagnosis and therapy of diabetes. The highest DR scores were calculated for those diagnosed before age 45, regardless of duration, therapy, or average blood glucose. Only individuals diagnosed before age 45 had high blood glucose concentrations in all categories of duration. These findings suggest that in this clinic population of Black women, those diagnosed with NIDDm before age 45 who eventually required insulin treatment were at the greatest risk of developing DR and that longterm poor glucose control is a contributing factor. These results suggest that greater emphasis be placed on this subgroup in allocating the limited resources available to improve the quality of glucose regulation, particularly through measures affecting compliance behavior.^ Findings concerning the association of DR with concentration of blood glucose and urine protein, blood pressure/hypertension and weight were compared with those reported from American Indian and Mexican American populations of the Southwestern United States where prevalence of NIDDM, hypertension and obesity is also high. Additional comparative analyses are outlined to substantiate the preliminary finding that there are systematic differences between these ethnic populations. ^

Investigating the effects of the 2007 Texas tobacco tax increase on the smoking behavior of adults

Smoking is major cause of premature mortality and morbidity in the United States. The health consequences of tobacco usage are increasingly concentrated in minority and lower socioeconomic groups. One of the most effective means of deterring tobacco consumption and generating revenue to fund prevention activities is the levying of excise taxes. In 2007 the state of Texas increased the excise tax on cigarettes by $1.00 per pack. This study sought to determine if there was a significant effect on smoking prevalence in the state by examining Behavioral Risk Factor Surveillance System (BRFSS) data for two years leading up to the tax increase-2005 and 2006- and two years post tax increase -2007 and 2008. Results were compared against a chi square distribution and three multiple logistic regression models were created to adjust for race/ethnicity, age, education and income. Results from this study show that there was not a significant decrease in smoking prevalence for most of the groups stratified by age, income and ethnicity. There was not a significant decrease in the younger adults aged 18-34 by income, ethnicity, or education. Smoking prevalence increased for some groups, e.g., Hispanic females. In the regression models, the tax effect was not significant. While overall prevalence decreased by 9%, there were not significant reductions among non-White or Hispanic survey participants. Taxed sales dropped by approximately 17% according to the Texas Comptroller. Without BRFSS data measuring daily cigarette consumption among current smokers, now not assessed, it is impossible to determine whether the discrepancy in reported prevalence and taxes sales is attributable to consumption of fewer cigarettes among smokers or tax avoidance.^
