Age period cohort analysis: a review of what we should and shouldn't do.

Authors:
Andrew Bell

Ann Hum Biol 2020 Mar;47(2):208-217

University of Sheffield, Sheffield, UK.

Age, period and birth cohort (APC) effects have been known for decades in biological, health and social sciences. However, exact collinearity between these three (Age = Year - Birth Year) leads to difficulty estimating these effects. It is thus impossible to estimate linear components of these effects without strong assumptions about at least one of these. Read More

Early life body size and its associations with adult bladder cancer.

Ann Hum Biol 2020 Mar;47(2):166-172

Center for Clinical Research and Prevention, Bispebjerg and Frederiksberg Hospital, The Capital Region, Frederiksberg, Denmark.

Adult overweight is a potential bladder cancer (BC) risk factor, but little is known about size earlier in life. To investigate if birth weight, childhood body mass index (BMI), height and growth are associated with adult BC. Anthropometric information from birth and ages 7-13 on 315,763 individuals born 1930-1989 in the Copenhagen School Health Records Register was linked to national registers. Read More

Evolutionary life history theory as an organising framework for cohort studies: insights from the Cebu Longitudinal Health and Nutrition Survey.

Ann Hum Biol 2020 Mar;47(2):94-105

Department of Anthropology, Northwestern University, Evanston, IL, USA.

By tracking a group of individuals through time, cohort studies provide fundamental insights into the developmental time course and causes of health and disease. Evolutionary life history theory seeks to explain patterns of growth, development, reproduction and senescence, and inspires a range of hypotheses that are testable using the longitudinal data from cohort studies. Here we review two decades of life history theory-motivated work conducted in collaboration with the Cebu Longitudinal Health and Nutrition Survey (CLHNS), a birth cohort study that enrolled more than 3000 pregnant women in the Philippines in 1983 and has since followed these women, their offspring and grandoffspring.

Assessing data linkage quality in cohort studies.

Ann Hum Biol 2020 Mar;47(2):218-226

Department of Population, Practice and Policy, UCL Great Ormond Street Institute of Child Health, London, UK.

Linkage of administrative data sources provides an efficient means of collecting detailed data on how individuals interact with cross-sectoral services, society, and the environment. These data can be used to supplement conventional cohort studies, or to create population-level electronic cohorts generated solely from administrative data. However, errors occurring during linkage (false matches/missed matches) can lead to bias in results from linked data. Read More

Medical Research Council Integrative Epidemiology Unit, Bristol Medical School (Population Health Sciences), University of Bristol, Bristol, UK.

Stress experienced by mothers during pregnancy can have both immediate and long-term effects on child development, potentially mediated by breastfeeding. Using a UK birth cohort study, we asked how maternal stress relates to breastfeeding and consequences for growth and puberty onset. We analysed data from the Avon Longitudinal Study of Parents and Children, collected via questionnaires and clinic visits (N: 698-8,506). Read More

School of Sport, Exercise and Health Sciences, Loughborough University, Loughborough, UK.

Cohort studies are special forms of longitudinal studies that have long been accepted as the primary designs to acquire information on the interaction between the environment and health and the subsequent aetiology and progression of disease. Richard Doll, Regius Professor of Medicine at Oxford University from 1969-1979, was the 20th century's pre-eminent epidemiologist in the UK. He used cohort studies to establish the relationship between smoking and health (primarily cancer) in the 1960s at a time when over 80% of British males smoked. Read More

The purpose of this study was to identify differences in growth and maturity related factors between those selected and deselected in youth sports teams and identify short-term associations with continued participation. Eight hundred and seventy participants, aged 11-17 years, were recruited from six sports try-outs in Saskatchewan, Canada: baseball, basketball, football, hockey, soccer and volleyball. Read More

Population structure of Han population in China revealed by 41 STR loci.

Ann Hum Biol 2020 Feb 5;47(1):65-69. Epub 2020 Jan 5.

Faculty of Forensic Medicine, Zhongshan Medical School of Sun Yat-Sen University, Guangzhou, People's Republic of China.

Currently, the Han population in China may be comprised of different genetic groups due to geographic, cultural and economic factors. Understanding population structure is very important for forensic purposes. However, knowledge of the genetic substructure within the whole Han population in China is still limited. Read More

Association of eating behaviour with clock gene polymorphism 3111 T > C in children based on nutritional status.

Ann Hum Biol 2020 Feb 31;47(1):76-80. Epub 2019 Dec 31.

Carrera de Nutrición y Dietética, Universidad San Sebastián, Concepción, Chile.

The CLOCK (circadian locomotor output cycle kaput) gene is a central regulator of circadian rhythm. The CLOCK gene has been related to energy intake and therefore to nutritional status. However, its specific associations with aspects of food behaviour in children have been scarcely investigated. Read More

Centre for Anatomy and Human Identification, University of Dundee, Dundee, UK.

Skeletal age estimations consistently under-age individuals with low body mass and over-age individuals with high body mass. To assess the directional biases of body size variables, including fat and muscle tissue, on skeletal age estimates. CT scans of 420 age- and size-selected cadavers were assessed using the fourth rib and pubic symphysis age estimation methods. Read More

Origin and identity of the Brokpa of Dah-Hanu, Himalayas - an NRY-HG L1a2 (M357) legacy.

Ann Hum Biol 2019 Dec 19;46(7-8):562-573. Epub 2019 Dec 19.

The Genographic Laboratory, School of Biological Sciences, Madurai Kamaraj University, Madurai, India.

The Brokpas are an isolated tribal population of the Dah-Hanu villages of the Leh district of India. They speak Dardic, a sub-branch of the Indo-European language family, and are putatively identified as "pure Aryan," a hegemonic impression perpetuated by foreign tourism. To determine if the above is true by looking for an appreciable frequency of NRY-HG-R1a1(M17) signatures which are common to Indo-European language speakers of mainland India and elsewhere.

Use of allometry and skinfold thicknesses to estimate the fat mass of circumpubertal boys.

Ann Hum Biol 2020 Feb 13;47(1):10-17. Epub 2019 Dec 13.

School of Nursing of Ribeirão Preto, University of São Paulo (USP), Ribeirão Preto, Brazil.

In the pubertal period, each part of the body grows at different rates. This makes the relationship between the parts nonlinear. Particularly, the fat mass (FM) of boys tends to decrease, further exacerbating the issue of linearity in growth. Read More

Prenatal exposure to oestrogens estimated by digit ratio (2d/4d) and breast size in young nulliparous women.

Ann Hum Biol 2020 Feb 13;47(1):81-84. Epub 2019 Dec 13.

Department of Human Biology, University of Wrocław, Wrocław, Poland.

Digit ratio (2d/4d) in humans is commonly used as a proxy for the exposure to oestrogens and androgens in prenatal life. Masculinisation/feminisation in adults may be also related to digit ratio and therefore to the oestrogen/androgen ratio in prenatal life. It has been shown, for instance, that Waist-to-Hip ratio (WHR) and the amount and distribution of body fat are related to digit ratio in women. Read More

Guizhou province is located in southwest China with abundant genetic, linguistic and cultural diversity. The Bouyei is one of the 18 officially recognised minority groups in Guizhou, accounting for about 97% of the total Bouyei population in China. However, the genetic history and forensic characterisation of the Bouyei people is largely unknown due to a lack of genetic data. Read More

Consanguineous unions and endogamy in families of beta-thalassaemia patients from two Mediterranean populations: Tunisia and Italy.

Ann Hum Biol 2019 Dec 3;46(7-8):610-615. Epub 2019 Dec 3.

Faculty of Médecine, University Tunis El Manar, Tunis, Tunisia.

Consanguinity increases the incidence of recessive diseases such as beta-thalassaemia major (βTM), one of the most prevalent lethal inherited diseases in the world. This study aims to identify the frequency of endogamy and consanguinity in two Mediterranean βTM populations and to study the implication of socio-economic factors. A trans-sectional study was conducted in 203 Tunisian families and 75 Italian families. Read More
