Christchurch Health and Development Study

Last updated

The Christchurch Health and Development Study is an ongoing long-term observational study of human health, based on study of a group of individuals born in Christchurch, New Zealand, in the 1970s. It has spawned over 500 papers [1] and many other experiments.

Overview

From April to August 1977, health researchers from the University of Otago, Christchurch, sought to enroll newborns as study participants. Ultimately, 1,265 children in Christchurch, representing over 97% of the births during the intake period, were enrolled in the study and followed into their 40s. [2] A wide variety of data was collected regarding family, personal and social circumstances over the time period. [2] Initial data were conducted at birth, four months, one year, every year to the age of 16, again at the age of 18 and at 21. [3]

By 2001, the study had produced results regarding unemployment, crime, substance abuse, breastfeeding, adolescent pregnancy, adoption, and other topics. [4] For example, the study found a strong correlation between duration of breastfeeding and academic outcomes in high school, building on previous research showing a change in IQ alone. [3]

The study also collected over 900 baby teeth to evaluate the impact of lead on behavioral and cognitive outcomes. [3]

A 40-year followup was conducted in 2019. [1]

<span class="mw-page-title-main">Adolescence</span> Human transition from puberty to adult

Adolescence is a transitional stage of physical and psychological development that generally occurs during the period from puberty to adulthood. Adolescence is usually associated with the teenage years, but its physical, psychological or cultural expressions may begin earlier or end later. Puberty typically begins during preadolescence, particularly in females. Physical growth and cognitive development can extend past the teens. Age provides only a rough marker of adolescence, and scholars have not agreed upon a precise definition. Some definitions start as early as 10 and end as late as 30. The World Health Organization definition officially designates an adolescent as someone between the ages of 10 and 19.

Alcohol abuse encompasses a spectrum of alcohol-related substance abuse, ranging from the consumption of more than 2 drinks per day on average for men, or more than 1 drink per day on average for women, to binge drinking or alcohol use disorder.

<span class="mw-page-title-main">Youth</span> Time between childhood and adulthood

Youth is the time of life when one is young. The word, youth, can also mean the time between childhood and adulthood (maturity), but it can also refer to one's peak, in terms of health or the period of life known as being a young adult. Youth is also defined as "the appearance, freshness, vigor, spirit, etc., characteristic of one, who is young". Its definitions of a specific age range varies, as youth is not defined chronologically as a stage that can be tied to specific age ranges; nor can its end point be linked to specific activities, such as taking unpaid work, or having sexual relations.

The Dunedin Multidisciplinary Health and Development Study is a detailed study of human health, development and behaviour. Based at the University of Otago in New Zealand, the Dunedin Study has followed the lives of 1037 babies born between 1 April 1972 and 31 March 1973 at Dunedin's former Queen Mary Maternity Centre since their birth. Teams of national and international collaborators work on the Dunedin Study, including a team at Duke University in the United States. The research is constantly evolving to encompass research made possible by new technology and seeks to answer questions about how people's early years have an impact on mental and physical health as they age.

<span class="mw-page-title-main">Childhood obesity</span> Obesity in children

Childhood obesity is a condition where excess body fat negatively affects a child's health or well-being. As methods to determine body fat directly are difficult, the diagnosis of obesity is often based on BMI. Due to the rising prevalence of obesity in children and its many adverse health effects it is being recognized as a serious public health concern. The term overweight rather than obese is often used when discussing childhood obesity, as it is less stigmatizing, although the term overweight can also refer to a different BMI category. The prevalence of childhood obesity is known to differ by sex and gender.

Gender dysphoria in children (GD), also known as gender incongruence of childhood, is a formal diagnosis for children who experience significant discontent due to a mismatch between their assigned sex and gender identity. The diagnostic label gender identity disorder in children (GIDC) was used by the Diagnostic and Statistical Manual of Mental Disorders (DSM) until it was renamed gender dysphoria in children in 2013 with the release of the DSM-5. The diagnosis was renamed to remove the stigma associated with the term disorder.

Emerging adulthood, early adulthood, or post-adolescence refers to a phase of the life span between late adolescence and early adulthood, as initially proposed by Jeffrey Arnett in a 2000 article from the American Psychologist. It primarily describes people living in developed countries, but it is also experienced by young adults in wealthy urban families in the Global South. The term describes young adults who do not have children, do not live in their own homes, and/or do not have sufficient income to become fully independent. Arnett suggests emerging adulthood is the distinct period between 20 and 29 years of age where young adults become more independent and explore various life possibilities.

<span class="mw-page-title-main">Breastfeeding and mental health</span>

Breastfeeding and mental health is the relationship between postpartum breastfeeding and the mother's and child's mental health. Research indicates breastfeeding may have positive effects on the mother's and child's mental health, though there have been conflicting studies that question the correlation and causation of breastfeeding and maternal mental health. Possible benefits include improved mood and stress levels in the mother, lower risk of postpartum depression, enhanced social emotional development in the child, stronger mother-child bonding and more. Given the benefits of breastfeeding, the World Health Organization (WHO), the European Commission for Public Health (ECPH) and the American Academy of Pediatrics (AAP) suggest exclusive breastfeeding for the first six months of life. Despite these suggestions, estimates indicate 70% of mothers breastfeed their child after birth and 13.5% of infants in the United States are exclusively breastfed. Breastfeeding promotion and support for mothers who are experiencing difficulties or early cessation in breastfeeding is considered a health priority.
