This study examined differences in the use of medications in two birth cohorts (born from 1916 to 1926 and from 1927 to 1937) among older elderly in the population-based cohort study in Bambuí, Minas Gerais State, Brazil. The study used data on participants who were 71-81 years of age in the baseline survey in 1997 (n = 492) and in the 11th wave, in 2008 (n = 620). The number of medications currently consumed (mean = 4.6 and 3.4, respectively) and prevalence of polypharmacy (46.6% and 29.1%, respectively) were higher in the more recent cohort as compared to the earlier one. These differences were independent of gender, age, schooling, number of medical visits in the previous 12 months, and number of chronic conditions. The more recent cohort showed significant differences in the use of psychoactive drugs, lipid modifying agents, drugs for diabetes, and antithrombotic agents, as well as changes in drugs used for arterial hypertension. In general, these changes are consistent with those observed in elderly populations in high-income countries.

The aim of this study was to evaluate the effect of birth cohort on nutritional status among older elderly (71-81 years old) from the Bambuí Cohort Study of Aging, conducted in Brazil in 1997 and 2008. We compared the two birth cohorts - 1916-1926 (older cohort) and 1927-1937 (recent cohort) - considering body mass index (BMI = weight/height²), waist circumference (WC) and prevalence of overweight (BMI ³ 27kg/m²). BMI (β = 0.09, 95%CI: 0.04, 0.15) and prevalence of overweight (PR = 1.02; 95%CI: 1.01; 1.03) were higher in the recent cohort than the earlier cohort, regardless of sex and schooling. No difference was observed in WC. Stratified by sex, similar overall trends were observed for men, and WC was higher in the recent cohort. Among women there was no difference in BMI and overweight, but WC was lower in the recent cohort. The cohort effect was greater among older men and, in the near future, may result in greater prevalence of overweight in this group.

Abstract Purpose: To investigate the associations of maternal excess weight before pregnancy with (1) weaning at age 3mo, (2) duration of exclusive breastfeeding at age 6mo, (3) duration of any breastfeeding at age 12mo; and (4) to compare the magnitude of these associations over four decades. Methods: Data were from participants in the Pelotas (Brazil) Birth Cohorts born in 1982 (N=5,334), 1993 (N=1,442), 2004 (N=4,092) and 2015 (N=4,102). Maternal pre-pregnancy weight was collected after the delivery and breastfeeding status was assessed when children were three and 12 months old. Results: Only in the most recent cohort (2015), women with excess weight [body mass index (BMI) ≥ 25 kg/m2) before pregnancy had higher risk of discontinuing exclusive breastfeeding within the first six months post-partum than women with normal weight [HR= 1.22 (95%CI 1.15; 1.30)]. Duration of any type of breastfeeding until 12 months of age was not affected by pre-pregnancy weight. Conclusion: Excess weight before pregnancy is associated with exclusive breastfeeding only in the most recent birth cohort coinciding with increases in weight excess and breastfeeding over time.

Patients Experience

Background: We evaluated the patient-partner experience in a longitudinal program called Integrated Population Medicine in the Sydney Medical School to assess its acceptability. The program exposed senior medical students to the lived experience of chronic disease. Methods: We surveyed 267 people with chronic conditions recruited as patient-partners by the 2012 student cohort in a mixed-methods longitudinal cohort study. Surveys were administered ‘over’ 18 months: before, during, and after the program. Results: A total of 155 (58%) patient-partners completed the baseline survey; 52 patients returned all 3 surveys. Patient-partners remained very positive about the program across all surveys. More than 95% of respondents enjoyed interacting with the student, and most were very positive about their role in teaching the student. Three major themes emerged: willingness to help, a sense of gratitude and enjoyment, and a chance to teach and learn. Participants were willing to discuss their illness experiences and were keen to spend more time with students. Conclusions: Patients are willing participants in longitudinal patient-partner programs. They perceive benefits for themselves and others, for the health system, and for students and would like to become more actively involved in medical education.

Prevalence Of Dementia

BackgroundIt is not clear whether the prevalence of dementia and depression among the elderly has changed during the past 30 years.MethodPopulation-based samples from Gothenburg, Sweden were examined with identical psychiatric and neuropsychiatric examinations at age 70 years in 1976–1977 (n = 404, response rate 78.8%) and 2000–2001 (n = 579, response rate 66.4%), and at age 75 in 1976–1977 (n = 303, response rate 78%) and 2005–2006 (n = 753, response rate 63.4%). Depression was diagnosed according to DSM-IV and dementia according to Kay's criteria. General linear models (GLMs) were used to test for differences between groups.ResultsDementia was related to age but not to birth cohort or sex. Major depression was related to sex (higher in women) but not to birth cohort or age. Minor depression was related to birth cohort, sex (higher in women), age (higher at age 75) and the interaction effect of birth cohort × age; that is, the prevalence of minor depression increased with age in the 2000s but not in the 1970s. Thus, the prevalence of minor depression was higher in 2005–2006 than in 1976–1977 among 75-year-olds for both men (12.4% v. 3.7%) and women (19.1% v. 5.6%) whereas there were no birth cohort differences at age 70.ConclusionsSecular changes were observed only for minor depression, which is considered to be related more to psychosocial factors than major depression. The high prevalence of minor depression in later-born birth cohorts emphasizes the importance of detecting minor depression in the elderly.

We use data from a population-based cohort of elderly Brazilians to assess predictors of hospitalizations during ten years of follow-up. Participants were 1,448 persons aged 60 years and over at baseline (1997). The outcome was self-reported number of hospitalizations per year. Slightly more than a fifth (23%) experienced no hospitalizations during the 10 year follow-up. About 30% had 1-2 events, 31% had between 3 and 7 events, and about 18% had 8 or more events during this time. Results of multivariable hurdle and Cox proportional hazards models showed that the risk of hospitalization was positively associated with male sex, increased age, chronic conditions, and visits to the doctors in the previous 12 months. Underweight was a predictor of any hospitalization, while obesity was an inconsistent predictor of hospitalization.

Abstract BackgroundThe China Northwest Cohort study (CNC), a community population-based prospective observational study, aimed to investigate specific aetiology causes of NCDs and the long-term health hazards of NCDs in the northwest region of China with different ethnic groups.Study design and methodsA total of 118,572 participants (aged 35–74 years and including the Han, Uygur, Kazakh, Hui and Tibetan ethnic groups from five provinces of northwest China) were recruited between June 2018 and May 2019. Approximately 10% of the participants will be actively followed every 3 years via face-to-face interviews with the use of concise questionnaires to review risk exposures and disease incidence, as well as to review biological specimens, including blood, saliva and stool samples, which will be collected. Passive follow-ups will be conducted by periodic linking (every 6 months) of baseline survey data to establish electronic disease registries. The questionnaire survey, a regular medical examination and the storage of blood samples were conducted in the CNC baseline survey for all of the participants. Several other items from the medical examination were recorded for approximately 40% of the participants.DiscussionAmong the total participants, the proportions of Han, Uygur, Kazakh, Hui and Tibetan ethnicities were 75.3%, 13.0%, 1.7%, 8.2% and 1.3%, respectively. Many lifestyle and medical history factors were different across the ethnic groups. The genetic information from the multi-ethnic individuals, combined with abundant personal and environmental information, provided an important opportunity to reveal complex and specific mechanisms of the genetic and environmental factors associated with NCDs.
