Familial environment in high- and middle-low-income municipalities: a survey in Italy to understand the distribution of potentially obesogenic factors.

OBJECTIVES: To explore the familial and social environment in high- and middle-low-income municipalities in Italy to evaluate the distribution of potentially obesogenic factors. A hybrid methodological approach was chosen. A survey of 1215 Italian children was performed to collect information regarding child, family and peer characteristics; additionally, income data were derived from national estimates based on zip codes. STUDY DESIGN: A cross-sectional study conducted via computer-assisted telephone interviews (CATI). METHODS: A CATI facility was used to interview 1215 Italian children aged 6-10 years. Information regarding family composition; body mass index (BMI) of the child, father and mother; mother's perception of the child's weight; levels of physical activity of the child, father and mother; time spent watching television or playing video games; use of social networks; leisure-time habits; and dietary habits of peers was collected. Income per year per person was obtained from the Italian National Institute of Statistics estimates. Municipalities were divided into two groups: one representing the highest ranking income from the total Italian income distribution, and one representing middle-low incomes. Differences between middle-low-income and high-income groups for child and parent BMIs, social networks, and dietary and leisure-time habits were compared using Wilcoxon and McNemar tests, as appropriate. Multivariate analysis was conducted using logistic regression. RESULTS: In total, 604 high-income children and 611 middle-low-income children were identified. A significant difference in father's BMI was found between middle-low- and high-income groups: 10.5% of fathers in middle-low-income municipalities were obese, compared with 3.8% in high-income areas (P < 0.001). On the contrary, this analysis found no association between income group and the mother's BMI. In this sample, middle-low-income children participated in less physical activity than high-income children (22.7% vs 34.8% participated in sporting activities for more than 3 h per week, P < 0.001), and spent more time in sedentary activities, such as watching television. However, middle-low-income children were not isolated and were surrounded by a wider social network than high-income children (80.4% vs 69% had more than three friends, P < 0.001). CONCLUSIONS: Significant differences were found in the distribution of obesogenic behaviours between middle-low- and high-income municipalities, suggesting that social factors as well as the physical environment should be considered in the development of health policies and interventions to reduce childhood obesity.

Nutritional profiles in a public health perspective: a critical review.

Nutritional profiling is defined as 'the science of categorizing foods according to their nutritional composition' and it is useful for food labelling and regulation of health claims. The evidence for the link between nutrients and health outcomes was reviewed. A reduced salt intake reduces blood pressure, but only a few randomized controlled trials have verified the effect of salt on overall and cardiovascular mortality. Evidence linking a reduced fat intake with cardiovascular mortality and obesity is generally non-significant. Studies that have examined the relationship between obesity and diet have produced contrasting results. A simulation exercise that demonstrated that the impact of a reduced salt and fat intake on overall mortality would be negligible in the European population was carried out. Consideration of the literature and the results of this simulation exercise suggest that the introduction of nutritional profiles in Europe would be expected to have a very limited impact on health outcomes.

The Severe Heart Failure Questionnaire: Italian translation and linguistic validation.

INTRODUCTION: The quality of life (QoL) is an important outcome indicator for heart failure management. As the use of a validate questionnaire in a different cultural context can affect data interpretation our main objective is the Italian translation and linguistic validation of the Severe Heart Failure Questionnaire (SHF) and its comparison with the MLHF (Minnesota Living with Heart Failure) Questionnaire. METHODS: The SHF and "The Minnesota Living with Heart Failure Questionnaire" were translated. A consensus involving parallel back-translations was established among a group of cardiologists, psychologists and biostatisticians. SHF and MLHF were both administrated to a sample of 50 patients. RESULTS: The patients' median age was 63 years. Ace inhibitors therapy was administered in 88% of cases and betablockers in 56% of cases. Finally the Italian version of SHF correlates well with MLHF for all domains, except life satisfaction SHF domain. DISCUSSION: The Italian version of the SHF correlates well with MLHF for almost all domains and it represents a valid alternative for quality of life assessment in heart failure patients.

[The SCOOP II trial in heart failure]. / Lo studio SCOOP II (Scompenso nell'Ospedalizzazione Pubblica): proposta di un modello.

BACKGROUND: The aim of this study was to evaluate the effectiveness of a health education intervention aimed at improving therapeutic compliance and quality of life of patients with chronic heart failure (CHF). In this 1100 bed Community hospital 97% of patients with CHF admitted to the Internal Medicine Unit have a high rate of readmission, mortality and negative quality of life. METHODS: Two hundred patients (123 males, 77 females, mean age 75 years) were enrolled and randomized. CHF patients admitted to the Internal Medicine Unit were randomly assigned to usual care (n=100) or intervention group (n=100), which consisted of a nurse-guided education program, facilitated telephone communication and regularly scheduled follow-up visits with an internist. The primary endpoints were quality of life and quality of service improvement, and improved compliance with the heart failure guidelines. All patients were submitted to echocardiography. RESULTS: Ejection fraction is available for 87% of them. Baseline quality of life is similar in both groups. Final data will be available after April 2001.

ASSENCE (assessment of cost-effectiveness of several strategies of early diagnosis in patients with acute chest pain and non-conclusive electrocardiogram).

Clinical, economical, organizative, and medico-legal issues raised by management of citizens who come to Emergency Department with acute chest pain and non diagnostic electrocardiogram are well known. Data from the Italian Health Ministry show that, in 1996, 37,444 patients had been discharged from Italian hospitals with the main diagnosis of chest pain. To obtain this "non-diagnosis", it was needed a mean hospital stay of 4.2 days with estimated costs close to $57,000,000. The ASSENCE study is a randomized, multicenter, international trial aimed at comparing three strategies of handling citizens presenting to emergency department for unexplained chest pain in terms of cost/effectiveness ratio and quality of patients' life. The three strategies that will be compared are: 1. current clinical protocols, prescribing an in-hospital observation period and discharge after several hours/days; 2. performing a dobutamine-atropine stress echocardiography between 0 and 18 hours after randomization (at 6 hours after index chest pain onset) and discharging the patients (if negative) immediately thereafter; 3. performing an electrocardiographic exercise stress test between 0 and 18 hours after randomization and discharging the patients (if negative) immediately thereafter. The main ASSENCE study end-point will be assessment of cost/effectiveness of the 3 strategies tested. Costs will be assessed taking into account: hospital stay length, performed diagnostic procedures and treatments during index admission, in-hospital and 2-month follow-up events (cardiac death, myocardial infarction, definite unstable angina, coronary angioplasty, by-pass surgery, re-admission to hospital for chest-pain). A secondary ASSENCE study end-point will be to assess the effect on patient quality of life of the use of the 3 strategies tested. Sample size estimation calculated in order to detect an absolute difference of at least 10% and based on a 30% expected rate of events, was of 186 patients for each strategy tested.
