Information regarding physical activity, sedentary behaviour, anthropometric index and family characteristics (structure, dynamics and functioning) was estimated by adolescents answering a questionnaire. The sample's average age was 16.07±1.09 years old, 56.3 % were female, 66.3 % had a low level of physical activity and 51.9 % were sedentary. A lack of physical activity occurred more frequently in females (56.8 % cf 41.5 %: p=0.000); family characteristics did not influence such risk behaviour. A relationship between physical activity and sedentary lifestyle with BMI could not be demonstrated, whilst waist circumference was associated with risky behaviour patterns. Teenagers in good health were more active (36.1 % cf 27 %) and less sedentary (49...

Risk perception helps to understand how rheumatoid arthritis patients perceive disease-related-risks. We developed and validated a risk perception questionnaire for Spanish speaking rheumatoid arthritis patients. Methods The questionnaire development and validation was performed in 3 steps, using respective convenience samples. Step-1 included the conceptual model construction, 20 patient's interviews to identify components from the conceptual model-dimensions and 11 healthcare provider´s consultations who identified RA related manifestations/complications (network and frequencies analysis). Step-2 consisted of item generation and reduction and questionnaire feasibility (n = 100). Step-3 consisted of the questionnaire psychometric validation (n = 270), which included content, face, construct (exploratory factor analysis) and criterion validity (logistic regression analysis) and consistency and stability (Cronbach's α and test-retest). Results Samples were representative of typical RA outpatients. Initial conceptual model included 7 dimensions, 3 for probability and 1 each, for responsibility, prevention, control and for severity (Step-1). The final version was considered feasible by the patients and included 27 items (Step-2). A five-factor model was most appropriated and resulted in 68.8% of the variance explained: Cronbach's α = 0.90, intraclass-correlation-coefficient = 0.93 (95% CI = 0.90-0.95). A positive relation between number of external criteria from the charts and risk perception was found; all items had �80% agreement from experts; patients agreed about iteḿ s semantic clarity (89%) and format adequacy (97%), (Step-3).

Periodic blood glucose screening in subjects at risk for developing diabetes may be necessary to implement preventive measures in patients prior to the manifestation of the disease and to efficiently diagnose diabetes. Not only medical aspects, but also psychological and social factors, such as the perception of risk (the individuals' judgment of the likelihood of experiencing an adverse event) influence healthy or preventive behaviors. It is still unknown if risk perception can have an effect on health behaviors aimed at reducing the risk of diabetes (glucose screening). The objective of study was to identify factors that influence glucose screening frequency. Eight hundred randomized interviews, which were stratified by socioeconomic level, were performed in Mexico City. We evaluated the perception of risk of developing diabetes, family history, health status and socioeconomic variables and their associa...

Our objective was to determine patient satisfaction with services rendered by health care personnel at the rheumatology outpatient consultation. Methods. We carried out a cross-sectional survey at a tertiary-level care hospital in Mexico City. A questionnaire on satisfaction with quality of medical care was applied to 347 adult patients who attended the outpatient rheumatology clinic at least twice and who agreed to participate. Questions in the instrument covered three aspects of quality of care, including structure, process, and results. Results. In overall assessment, 83.5% of patients reported satisfaction with care. Structure received worst score and process, the best. Outcomes (e.g., disease improvement) received intermediate scores. Correlations within these areas were strong but correlation with overall satisfaction was not high. The majority of patients stated that physician competence was the most valuable aspect of the visit; the least valuable was waiting time. Conclusions. Specific strategies need to be implemented to improve certain areas. Overall satisfaction as a measurement renders no specific and useful information due to complexity with regard to different dimensions of satisfaction. Ć 2004 IMSS.

The rates and life-time hip fracture risk are not known for Mexico, and for this reason, we studied the incidence of hip fractures, and the remaining life-time probability of having a hip fracture at the age of 50 years in Mexican men and women. All hip fracture cases registered during the year 2000 were collected at all the main tertiary-care hospitals in the two major health systems in México City, Instituto Mexicano del Seguro Social (IMSS) and Ministry of Health (SS), and the diagnosis was validated by chart review in all cases. The annual rates of hip fracture were 169 in women and 98 in men per 100,000 person-years. The life-time probability of having a hip fracture at 50 years of age was 8.5% in Mexican women and 3.8% in Mexican men. We conclude that hip fractures are an important health problem in Mexico and that Mexican health authorities should consider public health programs to prevent hip fractures.

Structured interviews were carried out with 500 health professionals employed at the Mexican Institute of Social Security in Mexico City. The Smith Salience Index was used to evaluate the relevance of concepts gathered from the free listings of the interviewees. Cluster analysis and factor analysis facilitated construction of the conceptual categories, which the authors refer to as ‘dimensions of ethical practice’. Six dimensions emerged from the analysis to define the qualities that comprise ethical clinical practice for Mexican health care providers: over-all quality of clinical performance; working conditions that favour quality of care; use of ethical considerations as prerequisites for any health care intervention; values favouring teamwork in the health professional–patient relationship; patient satisfaction scores; a...

The objective was to evaluate the quality of life of patients with leukemia and its relationship with psychological, familial and disease-related aspects. METHODS An analytic cross-sectional study was carried out in patients with acute leukemia at different stages of treatment. We used SF-36, Optimism and Family Cohesion scales. RESULTS Quality of life was affected physically and mentally in the treatment phases aimed to mitigate the active, and the advanced stage of this disease (50.6 ± 25.6, 62 ± 14.3; 46 ± 23.2, 53.8 ± 23.4, respectively), regardless of gender, age, level of optimism and family cohesion. Patients could carry out basic functions of self-care (bathing, feeding, etcetera), but not activities of daily living (shopping, household chores, etcetera), which require a greater effort. Although the patients perceiv...
