[Preventive practices of the residents over 25 years of age in Monterrey and its metropolitan area (Mexico)]. / Prácticas preventivas de los habitantes mayores de 25 años en Monterrey y su zona metropolitana (México).

BACKGROUND: Chronic and degenerative disorders are the leading causes of morbidity-mortality in Mexico, as a result of which the Health Sector has implemented preventive and suitable detection measures. The use of the health services is a dynamic behavior on the part of the population. In order for people to use these preventive measures, the barriers to accessing these services must be lessened. Hence, the objective of this study was that of ascertaining the use of the services for the detection of diabetes mellitus, high blood pressure, cervical-uterine and breast cancer and tetanus and diphtheria toxoide vaccinations. METHODS: The sample size was that of 254 individuals age 25 and over living in Monterrey or in the greater Monterrey metropolitan area. Those having employed preventive measures during the year immediately prior to the study were taken into account with regard to the use of preventive measures. The analysis consisted of descriptive statistics and bivariate analysis. RESULTS: Over 60% of the population was female, the average age being 42.3 + 14 years of age, three fourths of the population being on the social security rolls. A total 37% mentioned having undergone the diabetes test, and 44.5 the test for high blood pressure, while 31.1% had been vaccinated with the tetanus and diphtheria toxoide. Regarding specifically female checkups, 34.3% of all females had undergone the corresponding cervical-uterine cancer test, 29.5% having been screened for breast cancer. No relationship was found to exist between the use of measures and family histories and the perception of the importance of the checks. CONCLUSIONS: The use of preventive measures fall below some international standards. Individuals exposed to the risk must be sought in order to fittingly detect any chronic disorder.

[Impact of primary care on hospitalization of type 2 diabetics with equal conditions of health insurance]. / Impacto de la atención ambulatoria del primer nivel de atención en la hospitalización de población asegurada con diabetes mellitus tipo 2.

OBJECTIVE: To determine the impact of primary care on hospitalization of type 2 diabetics with equal conditions of health insurance. DESIGN: A case-control study. Case = diabetic hospitalized by a disease related condition. Control = diabetic without hospitalization during the last 12 months. SETTING: Urban primary care centers. PARTICIPANTS: Cases were consecutively selected from four out of five urban hospitals (n=123). Controls were chosen at random from primary care units matched by primary care source (n=135). Women with gestational diabetes were excluded as well as individuals with missing medical charts (approximately 15%). MEASUREMENTS: A primary care index was constructed with process and outcome indicators recommended by the American Medical Association, the Joint Commission on Accreditation of Healthcare Organizations, the National Committee for Quality Assurance, the American Diabetes Association and the Official Mexican Standards. Compliance to less than 60% of recommendations was considered unsatisfactory primary care. RESULTS: The following were hospitalization risk factors: less than 2 visits to family physician during the last year (OR adjusted, 16,2; 95% CI, 1,5-174,2), glucose level (OR adjusted, 1,006; 95% CI, 1,002-1,010) and cognitive level (OR adjusted, 0,98; 95% CI, 0,96-0,99), in addition to exercising and year of diagnosis. Sixty-five percent of cases observed unsatisfactory primary care compared with 49,1% of controls (P=0,03). Unsatisfactory primary care increased 2,5 times the risk of hospitalization (95% CI, 1,2-5,0) (pseudo R2=0,279; P<0,001). CONCLUSIONS: Primary care is a potential factor for reducing hospitalization of type 2 diabetics. Effective primary care programs would contribute to a better disease control and less unnecessary hospitalizations.

[Health needs of the diabetic user of primary care]. / Necesidades en salud del diabético usuario del primer nivel de atención.

OBJECTIVE: To determine the extent and importance of unmet health needs of type 2 diabetic patients seen at primary care services. MATERIAL AND METHODS: A cross-sectional study was conducted in 1999, among rural and urban patients of the Mexican Institute of Social Security, in Nuevo Leon, Mexico. The study population consisted of 256 subjects selected at random, diagnosed with type-II diabetes for at least two years. Data were obtained by interview and complemented with medical charts and provider interviews. Five health areas and four health determinants were evaluated, through Mexican Official Standards and American Diabetes Association standards of medical care for diabetic patients. Analysis consisted of descriptive statistics and estimation of z scores. RESULTS: Health needs were met in 49% of cases. A lower mean of health need satisfaction was found in rural regions as compared to urban regions (36.8% vs. 53.3%, p < .01). Nutrition was the most affected health area (z score = -6), followed by the physical exercise (z score = -1), the metabolic health area (z score = +1), the non-smoking health area (z score = +2), the prevention and early detection of complications health area (z score = +2), and the cognitive health area (z score = +3). The health determinant with the highest requirement corresponded to utilization (z score = -5), followed by resource availability (z score = -4), perceived health need (z score = +4), and access barriers (z score = +6). CONCLUSIONS: Health need measurement allows evaluating the effectiveness of existing interventions, in addition to identifying areas with higher unmet health needs. These findings facilitate analysis and decision-making to devise specific health policies and actions directed at improving the quality of care for diabetic patients.

[Nutritional risk in patients with pulmonary tuberculosis: the patient's or the health services' problem?]. / Riesgo nutricional en pacientes con tuberculosis pulmonar: cuestión del paciente o de los servicios de salud?

OBJECTIVE: To determine nutritional risk factors in a population of patients with pulmonary tuberculosis (PT). MATERIAL AND METHODS: During 1997, one-hundred and eighty-five patients with PT were chosen at random from two health institutions in Monterrey, Nuevo León, México. Variables analyzed were: anthropometric measures, socioeconomic status, utilization of the nutrition clinic, access to foodstuffs, adverse reactions to drugs, and disease attributable to malnutrition. Statistical analysis consisted of descriptive, bivariate, and multivariate logistic regression, in addition to prevalence ratios and 95% confidence intervals. RESULTS: The mean age was 42.4 +/- 19.9 years. The mean body mass index was 19.8 +/- 3.2; 57% of patients presented malnutrition; 26% of them were referred to the nutrition clinic, 24.3% of whom actually attended it. Multivariate analysis showed that adverse reactions of tuberculosis drugs were risk factors for malnutrition, independent of age, gender, education, occupation, year of diagnosis and access to foodstuffs, disease attributable, and utilization of the nutrition clinic. (chi 2 = 10.58; p = 0.051, R2 = 0.42). CONCLUSIONS: Nutritional risk in patients with pulmonary tuberculosis is both a patient and a health services issue. The high prevalence of malnutrition, the low utilization rate of nutritional services, and the effect of adverse reactions to therapeutic drugs, justify the need to focus attention on this particular group of patients.

[Assessment of accessibility to health services facilities]. / Evaluación de la accesibilidad en los servicios de salud.

OBJECTIVE: To assess health care access integrating the availability of resources, medical institution and the patient point of view. SETTING: Nuevo León, México. MEASUREMENTS AND MAIN RESULTS: A random sample of patients were interviewed about their perceptions on different barriers, which also were assessed for the institution utilizing the corresponding indicator. Availability of resources were also measured for every primary and secondary medical care unit of the greatest Mexican health care system in Nuevo León. It was observed a 70% access; 70% for primary care and 73% for secondary care. Availability of human resources was an important factor but barriers as observed by the institution were the most important (waiting time and traveling cost). Barriers were rated different by the institution and the patient. CONCLUSIONS: The combination of institutional barriers, patient barriers and resources for assessing health care access is discussed.

Evaluación de la accesibilidad en los servicios de salud / Access. Barriers. Availability of resources

Objetivo. Evaluar la accesibilidad de los servicios de salud integrando la disponibilidad de recursos, el punto de vista de la institución médica y del paciente. Emplazamiento. Zona metropolitana del estado de Nuevo León, México. Mediciones y resultados principales. Una muestra de pacientes elegida al azar fue entrevistada sobre percepciones a distintas barreras, las mismas que fueron evaluadas para la institución utilizando el indicador correspondiente. La disponibilidad de recursos fue también identificada para todas las unidades médicas de primero y segundo nivel del sistema de salud mexicano más grande en Nuevo León. La accesibilidad fue limitada, 70 por ciento para atención primaria y 73 por ciento para atención en segundo nivel. La disponibilidad de recursos humanos fue importante, pero las barreras observadas por la institución fueron las principales (tiempo de espera y coste de traslado). Las barreras fueron evaluadas de diferente manera por los usuarios y la institución. Conclusiones. La determinación de la accesibilidad a través de la integración de la medición de los recursos, de las barreras evaluadas por la institución y las percibidas por el usuario es discutida (AU)

The cost of diabetes mellitus and its impact on health spending in Mexico.

BACKGROUND: The objective of this study was to determine the cost of diabetes mellitus, its impact on health spending in Mexico, and its percentage of the gross domestic product (GDP). METHODS: There was a four-stage approach: identification of the epidemiology of the use of health services; estimate of treatment cost; determination of the diabetic population, and calculation of the percentage of health spending. RESULTS: The average annual cost per diabetic patient was $708 U.S. dollars (USD), the total annual cost of diabetics was $2,618,000 USD, the percentage of health spending was 15.48%, and the percentage of the GDP was 0.79%. CONCLUSIONS: It is necessary to seek strategies that allow for a more efficient use of resources designated for type 2 diabetes treatment.

[Malnutrition in pre-school infants in migrant families]. / Desnutrición en prescolares de familias migrantes.

OBJECTIVE: To compare malnutrition rates between migrant and non-migrant children. MATERIAL AND METHODS: One-hundred and sixty children 1-6 years old were selected at random from schools located in highly marginated areas. Excluded were infants with congenital malformations or under nutritional intervention. Migration was defined as any geographical movement during the last 6 years. Malnutrition was assessed through the weight/height and height/age indicators, as recommended by the World Health Organization. RESULTS: Fifty-nine percent of the infants belonged to families whose father had a non-qualified occupation, 27.5% of them did not finish elementary school. Fifty-three referred migration; malnutrition rate was 51.3% among migrant infants and 28.8%, among non-migrant infants (OR = 2.6, CI 95% = 1.2, 5.2, p = 0.006). Migrant children registered a mean Z score of -2.4 +/- .40 and non-migrant children, -2.3 +/- .33, based on the indicator height for age. CONCLUSIONS: Chronic malnutrition among migrant infants justifies a nutritional intervention, they constitute a specific group at risk. Migration should be considered for health planning.
