The prevalence of chronic diseases and major disease risk factors at different ages among 150 000 men and women living in Mexico City: cross-sectional analyses of a prospective study

<p>Abstract</p> <p>Background</p> <p>While most of the global burden from chronic diseases, and especially vascular diseases, is now borne by low and middle-income countries, few large-scale epidemiological studies of chronic diseases in such countries have been performed.</p> <p>Methods</p> <p>From 1998–2004, 52 584 men and 106 962 women aged ≥35 years were visited in their homes in Mexico City. Self reported diagnoses of chronic diseases and major disease risk factors were ascertained and physical measurements taken. Age- and sex-specific prevalences and means were analysed.</p> <p>Results</p> <p>After about age 50 years, diabetes was extremely common – for example, 23.8% of men and 26.9% of women aged 65–74 reported a diagnosis. By comparison, ischaemic heart disease was reported by 4.8% of men and 3.0% of women aged 65–74, a history of stroke by 2.8% and 2.3%, respectively, and a history of cancer by 1.3% and 2.1%. Cancer history was generally more common among women than men – the excess being largest in middle-age, due to breast and cervical cancer. At older ages, the gap narrowed because of an increasing prevalence of prostate cancer. 51% of men and 25% of women aged 35–54 smoked cigarettes, while 29% of men and 41% of women aged 35–54 were obese (i.e. BMI ≥30 kg/m²). The prevalence of treated hypertension or measured blood pressure ≥140/90 mmHg increased about 50% more steeply with age among women than men, to 66% of women and 58% of men aged 65–74. Physical inactivity was highly prevalent but daily alcohol drinking was relatively uncommon.</p> <p>Conclusion</p> <p>Diabetes, obesity and tobacco smoking are highly prevalent among adults living in Mexico City. Long-term follow-up of this and other cohorts will establish the relevance of such factors to the major causes of death and disability in Mexico.</p

1068-P: Diabetes and Comorbidities Risk Assessment in Hospitalization and Fatalities from the Mexican COVID-19 Surveillance System

The SARS-CoV-2 outbreak poses a challenge to the Mexican health care system due to its high complication and lethality rates in patients with diabetes and comorbidities. Here, we evaluate the association among diabetes and main comorbidities [obesity, hypertension and chronic kidney disease (CKD)] on COVID-19 outcomes (prevalence, hospitalization, lethality and hospital fatality) in Mexican population. We used available public data released by the Mexican COVID-19 surveillance system (MC-19SS) from January 1st to December 31st of 2020. All 3,401,172 records of SARS-CoV-2 suspected population over or equal to 20 years old were included, out of whom 1,384,470 tested positive. Multiple logistic regression models were fitted to assess the risk over several outcomes (hospitalization and fatality), with self-reported diabetes and comorbidities in confirmed cases, adjusting for age, sex, smoking status and marginalization of the place of residence. Overall population tested, 399,953 (11.8%) subjects had diabetes. Of them, 47.8% also had hypertension, 9.0% obesity and 7.0% CKD. Patients who tested positive to COVID-19 had a higher proportion of diabetes (14.7%). From the 203,310 COVID-19 positive patients with diabetes, 95,225(46.8%) were hospitalized and of those 45,128(47.4%) died; also 4,701 died without had been hospitalized. People with diabetes had significant (p&amp;lt;.005) higher odds of hospitalization OR:2.2, hospital 1.27 and non-hospital 1.98 fatality. Nevertheless, subjects with diabetes and other chronic disease experience higher rates of several outcomes. Diabetes and CKD had the highest odds of hospitalization 7.3 died in hospital (2.14) or out of hospital (6.5) compared with cases without diabetes. This analysis points out that diabetes contributes to the risk of infection and worse outcomes for those infected by SARS-CoV-2. More must be done to combat and prevent diabetes and comorbidities to reduce the burden of COVID-19. Disclosure H. Gallardo-rincón: None. A. Montoya: None. L.

Multilevel analysis of hepatitis A infection in children and adolescents: a household survey in the Northeast and Central-west regions of Brazil

Background The objectives were to estimate the prevalence of hepatitis A among children and adolescents from the Northeast and Midwest regions and the Federal District of Brazil and to identify individual-, household- and area-levels factors associated with hepatitis A infection

Human papillomavirus infections in women seeking cervical Papanicolaou cytology of Durango, Mexico: prevalence and genotypes

BACKGROUND: HPV infection in women from developing countries is an important public health problem. Therefore, we sought to determine the prevalences of HPV infection and HPV genotypes in a female population of Durango City, Mexico. Also to determine whether any socio-demographic characteristic from the women associated with HPV infection exists. METHODS: Four hundred and ninety eight women seeking cervical Papanicolaou examination in three public Health Centers were examined for HPV infection. All women were tested for HPV DNA PCR by using HPV universal primers. In addition, all positive HPV DNA PCR samples were further analyzed for genotyping of HPV genotype 16, 18 and 33. Socio-demographic characteristics from each participant were also obtained. RESULTS: Twenty-four out of four hundred and ninety-eight (4.8%) women were found infected by HPV. HPV genotype 16 was found in 18 out of the 24 (75%) infected women. Two of them were also coinfected by HPV genotype 18 (8.3%). In the rest 6 PCR positive women, genotyping for HPV genotypes 16, 18 and 33 were negative. CONCLUSION: The prevalence of HPV in women of Durango City is low; however, most infected women have high risk HPV genotype. The women who were studied showed low frequency of risk factors for HPV infection and this may explain the low prevalence of HPV infection. The high frequency of high risk HPV genotypes observed might explain the high rate of mortality for cervical cancer in our region

Does Proximity to Retailers Influence Alcohol and Tobacco Use Among Latino Adolescents?

Despite decades of research surrounding determinants of alcohol and tobacco (A&T) use among adolescents, built environment influences have only recently been explored. This study used ordinal regression on 205 Latino adolescents to explore the influence of the built environment (proximity to A&T retailers) on A&T use, while controlling for recognized social predictors. The sample was 45% foreign-born. A&T use was associated with distance from respondents’ home to the nearest A&T retailer (−), acculturation (+), parents’ consistent use of contingency management (−), peer use of A&T (+), skipping school (+), attending school in immediate proximity to the US/Mexico border (+), and the interaction between the distance to the nearest retailer and parents’ consistent use of contingency management (+). The association between decreasing distance to the nearest A&T retailer and increased A&T use in Latino adolescents reveals an additional risk behavior determinant in the US–Mexico border region
