Telephone Coverage and Health Survey Estimates: Evaluating the Need for Concern About Wireless Substitution

We sought to determine whether the exclusion of adults without landline telephones may bias estimates derived from health-related telephone surveys. We took data from the 2004 and 2005 National Health Interview Survey and used logistic regression to compare the odds of behavioral risk factors and health care service use for adults with landline telephones to those for adults with only wireless telephones and adults without any telephone service. When interviewed, 7.2% of adults, including those who did and did not have wireless telephones, did not have landline telephones. Relative to adults with landline telephones, adults without landline telephones had greater odds of smoking and being uninsured, and they had lower odds of having diabetes, having a usual place for medical care, and having received an influenza vaccination in the past year. As people substitute wireless telephones for landline telephones, the percentage of adults without landline telephones has increased significantly but is still low, which minimizes the bias resulting from their exclusion from telephone surveys. Bias greater than 1 percentage point is expected only for estimates of health insurance, smoking, binge drinking, having a usual place for care, and receiving an influenza vaccination.

No Symptoms, No Asthma: The Acute Episodic Disease Belief Is Associated With Poor Self-Management Among Inner-City Adults With Persistent Asthma

Asthma morbidity and mortality is highest among inner-city populations. Suboptimal beliefs about the chronicity of asthma may perpetuate poor asthma control among inner-city asthmatics. This study sought to characterize beliefs about the chronicity of disease and its correlates in a cohort of inner-city adults with persistent asthma.Prospective, longitudinal, observational cohort study.One hundred ninety-eight adults hospitalized with asthma over a 12-month period at an inner-city teaching hospital.Sociodemographics, clinical history, disease beliefs, and self-management behaviors were collected by interview. Information on self-reported use of inhaled corticosteroids (ICS), peak flowmeters, and regular asthma visits was collected during hospitalization, and 1 month and 6 months after discharge.This cohort was predominantly low income and nonwhite, with high rates of prior intubation, oral steroid use, and emergency department visits and hospitalizations. Overall, 53% of patients believed they only had asthma when they were having symptoms, what we call the no symptoms, no asthma belief. Men patients, those > or = 65 years old, and those with no usual place of care had greater odds of having the no symptoms, no asthma belief, and those receiving oral steroids all or most of the time or with symptoms most days had half the odds of having this belief (p < 0.05 for all). The no symptoms, no asthma belief was negatively associated with beliefs about always having asthma, having lung inflammation, or the importance of using ICS, and was positively associated with expecting to be cured. The acute disease belief was associated with one-third lower odds of adherence to ICS when asymptomatic at all three time periods (p < 0.02 for all).The single question, "Do you think you have asthma all of the time, or only when you are having symptoms?" can efficiently identify patients who do not think about or manage their asthma as a chronic disease.

Utilization of Preventive Care by Haitian Immigrants in Miami, Florida

In order to evaluate the health needs and consequences of barriers to health care access for the Haitian immigrant community of Miami-Dade County, Florida, we collected in 2001 demographic and health needs and access data from a probability sample of county residents of Haitian origin. We computed frequencies and prevalence ratios, and employed chi-square and logistic regression methods for data analysis. Hypertension and diabetes were among the most prevalent health conditions mentioned. Up to 39% of participants failed to have an annual physical and 10% failed to receive care for their serious health conditions. On bivariate analysis, insurance coverage, a usual place of care, educational attainment, household income, citizenship status, and duration of residency were associated with services utilization. Citizenship status was the strongest independent predictor of services utilization. The findings suggest that this community faces distinct health needs and daunting challenges to meet those needs.

Children in the United States with Discontinuous Health Insurance Coverage

Estimates of the number of uninsured people in the United States usually exclude those with discontinuous coverage. The effects of gaps in insurance coverage for children on access to and use of ambulatory care are poorly understood. We analyzed a sample of 26,955 children under 18 years of age from the 2000 and 2001 National Health Interview Surveys. Children with discontinuous health insurance coverage were compared with those who were uninsured all year and with those who had public or private full-year coverage. During the last 12 months before they were interviewed, 6.6 percent of children in the United States had no insurance and an additional 7.7 percent had gaps in insurance. Children who had full-year insurance coverage (private or public) had low rates of unmet health care needs and good access to care (delayed care, unmet medical care, and unfilled prescriptions were reported in <3 percent, and <5 percent had no usual place of care). Access to care was much worse for children who were uninsured for part of the year and for those who were uninsured for the full year (delayed care, 20.2 percent and 15.9 percent, respectively; unmet medical care, 13.4 percent and 12.6 percent, respectively; unfilled prescriptions, 9.9 percent and 10.0 percent, respectively; P<0.01 for all comparisons with children with full-year, private insurance coverage). In multivariate analyses adjusting for age, income, race or ethnic group, region, citizenship, family structure, parental employment, and health status, the differences in access to care persisted. As compared with the parents of children with full-year, private insurance, parents of children uninsured for the full year were far more likely to report delaying care (adjusted odds ratio, 12.65; 95 percent confidence interval, 9.45 to 16.94), as were parents of children uninsured for part of the year (adjusted odds ratio, 13.65; 95 percent confidence interval, 10.41 to 17.90). Children with gaps in health insurance coverage commonly do not seek medical care, including preventive visits, and do not get prescriptions filled. These findings are important for both research and policy and point to the need for more encompassing and sensitive measures of the situation of being uninsured.

Racial and ethnic differences in asthma diagnosis among children who wheeze.

Racial and ethnic disparities exist in reported childhood asthma prevalence, but it is unclear if disparities stem from true prevalence differences or a different likelihood of receiving a diagnosis from a health professional. Concern has been raised that asthma may be underdiagnosed, particularly among minority children who have more restricted access to high-quality health care. To examine racial/ethnic differences among currently symptomatic children in acquiring an asthma diagnosis to determine if relative underdiagnosis among minorities exists. Children for whom no symptoms were reported (a group that includes those with well-controlled symptoms) were excluded from the analysis. The 1999 National Health Interview Survey includes a nationally representative sample of children with reported wheezing symptoms. We included children 3 to 17 years old in the study and analyzed racial/ethnic differences in asthma diagnosis, controlling for young age, gender, parental education, single-parent household, central-city residence, region of residence, health insurance, having a usual place of care, and parent-reported severity of wheezing symptoms. Among those reported to have wheezed in the past year (n = 946), 83% of Puerto Rican, 71% of non-Hispanic black, and 65% of Mexican children were diagnosed with asthma compared with 57% of non-Hispanic white children. Using non-Hispanic white children as the reference group, the approximate adjusted relative risk for physician diagnosis of asthma given wheezing in the past year was 1.43 (95% confidence interval [CI]: 1.04, 1.63) for Puerto Rican, 1.22 (95% CI: 1.03, 1.37) for non-Hispanic black, and 1.19 (95% CI: 0.94, 1.39) for Mexican children. Minority children were reported to have greater severity of wheezing symptoms. Even after accounting for this increased severity, children in racial and ethnic minority groups were as or more likely to have a reported asthma diagnosis than non-Hispanic white children. Our findings do not provide evidence for the hypothesis that symptomatic minority children are underdiagnosed with asthma compared with non-Hispanic white children. To the contrary, among currently symptomatic children, minority children were more likely to be diagnosed than non-Hispanic white children even after accounting for the higher wheezing severity among minority children.

Skin cancer screening among U.S. adults from 1992, 1998, and 2000 National Health Interview Surveys

Background. Relatively little is known about the prevalence of skin cancer screening in the context of inconsistent skin cancer screening recommendations. Methods. To determine the prevalence and predictors of skin cancer screening rates in the U.S. adult population, we used self-reported data from the 1992, 1998, and 2000 National Health Interview Surveys, a nationally representative survey of civilian noninstitutionalized adults. Results. The percentage of the U.S. adult population who had ever had a skin examination conducted by a doctor was 20.6% in 1992, 20.9% in 1998, and 14.5% in 2000. The percentage with a recent skin examination was 10.3% in 1992, 11.0% in 1998, and 8.0% in 2000. White non-Hispanics reported being screened more frequently than persons in other racial or ethnic groups. Recent skin cancer screening exams were more common among white persons who had a family history of melanoma, had higher education, had usual place of care, and were older (≥50 years). Frequent use of sunscreen and hats was associated with a recent skin cancer exam. Conclusions. In the past decade, skin cancer screening rates have been consistently low. Continued monitoring of skin cancer examination is important given conflicting current research results and potentially evolving science.

Differences in access to health care services among adults in rural America by rural classification categories and age.

To study differences in excess to health care services between different population groups in rural areas of the United States. Using data from the 1994 National Health Interview Survey and the 1991 Area Resource File, we examined the differences in excess with seven measures: having a regular source of care, having a usual place of care, having health insurance coverage, delaying medical care because of cost for all rural residents; number of doctor visits, number of hospital discharges and length of hospital stay per discharge for those who reported their health as being either poor or fair. Rural residents were classified by ages and grouped into four rural classification categories that were characterised along two dimensions: adjacent to a metropolitan statistical area (MSA) (yes/no) and inclusion of a city of at least 10,000 people (yes/no). Rural areas. Rural populations. Residents aged 18-24 years had the worst access to services and the residents aged 65 years and over had the best access to services when measured by regular source of care, a usual place of care and health insurance status. Compared to those aged 50-64 years, residents aged 25-49 years were less likely to report having health insurance and more likely to report delaying seeking medical care because of costs. Rural residents who lived in a county adjacent to an MSA generally were less limited in access than those who lived in a county not adjacent to an MSA. Rural America is not a homogeneous entity in many aspects of the access to health care services.

DETERMINING DENTAL CHECKUP FREQUENCY

The authors assessed the dental checkup frequency of adults living in the Detroit tricounty area and identified demographic, access and subjective factors associated with visits to a dentist made not because of a dental problem. Data are from a 1994 probability-based sample of adults who were interviewed and received an in-home oral examination. The authors used the variables of age, sex, education level, income level, dental insurance status, usual place for care, objective measures of oral health, and subjective assessments of health, pain and dental anxiety to predict the frequency of dental checkups. The authors found that differences in dental checkup behavior were related to demographics, access to dental care, subjective ratings of oral and general health and other self-assessments, and clinical parameters of oral health. In multiple logistic regression analysis considering all variables simultaneously, sex, income, having a usual place for care and level of dental care anxiety were found to be associated with having dental checkups. The authors determined the statistical significance level at P < .05. A total of 69.7 percent of the study population reported having had a dental checkup at least once a year in the past five years. The authors found that four factors associated with infrequent dental checkups: being male, having lower income levels, not having a usual place for care and being anxious about receiving dental care. Dental health professionals should consider the correlates of dental checkup frequency identified in this study and the usefulness of proposed strategies to increase and sustain regular preventive visitation patterns in their own patient populations.
