Abstract Background : Research using linked routine population-based data collected for non-research purposes has increased in recent years because they are a rich and detailed source of information. The objective of this study is to present an approach to prepare and link data from administrative sources in a middle-income country, to estimate its quality and to identify potential sources of bias by comparing linked and no-linked case. Methods: We linked two administrative datasets with data covering the period 2001 to 2015, using maternal attributes (name, age, date of birth, and municipally of residence) from Brazil: live birth information system and the 100 Million Brazilian Cohort (created using administrative records from over 114 million individuals whose families applied for social assistance via the Unified Register for Social Programmes) implementing an in house developed linkage tool CIDACS-RL. We then estimated the proportion of highly probably link and examined the characteristics of missed-matches to identify any potential source of bias. Results: A total of 27,699,891 live births linked with maternal information recorded in the baseline of the 100 Million Brazilian Cohort dataset of those, 16,447,414 (59.4%) children were found registered in the 100 Million Brazilian Cohort dataset. The proportion of highly probably link ranged from 39.3% in 2001 to 82.1% in 2014. A substantial improvement in the linkage after the introduction of maternal date of birth attribute, in 2011, was observed. Our analyses indicated a slightly higher proportion of missing data among missed matches and a higher proportion of people living in an urban area and self-declared as Caucasian among linked pairs when compared with non-linked sets. Discussion: We demonstrated that CIDACS-RL is capable of performing high quality linkage even with a limited number of common attributes, using indexation as a blocking strategy in larg e routine databases from a middle-income country. However, residual records occurred more among people under worse living conditions. The results presented in this study reinforce the need of evaluating linkage quality and when necessary to take linkage error into account for the analyses of any generated dataset.

Abstract BackgroundThe Bangkok falls study aimed to identify fall-associated factors, including home healthcare hazards, nutritional status, hydration status, sarcopenia, frailty, locomotive syndrome, and health status of urban older adults in a middle-income country.Methods This was a population-based cohort study that enrolled adults who lived in Bangkok, Thailand. Our study recruited older adults aged ≥ 60 years old, able to walk, and expected to live in the community for at least 2 years. The study had three phases included; phase 1: subject identification and terminology clarification. Phase 2: we collected data at community sites on baseline characteristic and fall risk identification. Examinations and laboratory investigations were scheduled for one month later. Phase 3: telephone follow up for falls rate, functional status and death at 3, 6, 12 months.Results A total 1,001(51.84%) people were enrolled for our study. The average age of our study was 69.9 years old (SD, 6.8), and two-thirds were female. Using “Stopping Elderly Accidents, Death and Injuries” (STEADI) screening fall risk, our study found that 37.7% had scores ≥ 4, which means that there is a risk of fall. In addition, the risk of falls increased among older adults aged 75–84 years (49.5%) and older adults aged ≥ 85 years (67.7%) (P-value < 0.001).ConclusionThis study demonstrated the feasibility of conducting a population-based cohort study among urban older adults in a middle-income country using the local community healthcare system. Our study have a tendency to provide data source for fall risk factors and disability in older adults.

Results A total of 27,699,891 live births were recorded of those, 16,447,414 (59.4%) were linked with SINASC. The sensitivity of the linkage ranged from 39.3% in 2001 to 82.1% in 2014.
