Sleep and sleep habits

Sleep and sleep habits comprises questions about the amount of sleep and sleeping habits, such as "How many hours a night do you sleep on average during a school week/working week?", "How much does your twin sleep?", and "Do/did the twins sleep together in the same room?"

Mode of collection	SelfAdministeredQuestionnaire
Analysis unit	Individual

Purpose	The research carried out by the Netherlands Twin Register focuses on the role of heritability in mental and physical health. For instance, the NTR investigates why some people become more easily depressed than others, or why certain people get diabetes while others do not. Other research areas include lifestyle and habits that influence health and disease, such as smoking, drinking and exercise.

YS_2 Wave

Wave alternate title	YNTR survey age 2 YS_2
Short description of the wave	The YS_2 survey gathers maternal report (fathers added in 2014) on motor development, breastfeeding, health, handedness and growth data (including height and weight) as obtained from the Dutch National Health Services (from 2010) in 2-year old twins (mean age = 2.35 years, SD = 0.30 years). From 2008 onwards, items on wellbeing, child care, and temperament were added to the surveys.

YS_5 Wave

Wave alternate title	YNTR survey age 5 YS_5
Short description of the wave	The YS_5 survey is sent to the mothers around the 5th birth year of the twins (mean age = 5.52 years, SD = 0.55 years). The survey includes items on child care and school, growth, zygosity, toilet training, asthma and eczema, fine motor coordination, language development, and problem behaviors as assessed by a short version of the Devereux Child Behavior Checklist (DCB). The booklet includes an extra section for fathers of twins to report about behavior problems. From 2011 onward, items on child care and school, living and family situation were updated and items on wellbeing were added. From the second half of 2015 the short form of the Childhood Behavior Questionnaire (CBQ) was added. From 2017 the surveys no longer have a separate section for the father.

YS_DHBQP Wave

Wave alternate title	Dutch Health and Behavior Questionnaire - pilot YS_DHBQP
Short description of the wave	In this pilot project, the Dutch Health and Behavior Questionnaire (DHBQ) was developed at the department of Biological Psychology of the VU University. It is a collection of standardized questions targeting multiple domains. The focus of the survey is on emotional and behavioral problems assessed by the Youth Self-Report (YSR), subjective wellbeing, lifestyle, exercise behavior, sedentary behavior, and family functioning. The pilot was sent to 14-, 16-, and 18-year old twins (mean age = 16.6 years, SD = 0.60 years) born between 1993 and 1990 and their 12-25 year old siblings (mean age = 17.5 years, SD = 3.08 years) born between 1981 and 1991.

YC_BS2 Wave

Wave alternate title	Brain Scale measurement 2 YC_BS2, Brain Scale measurement t1, BrainScale age 12
Short description of the wave	The YC_BS2 project was the second measurement in the Dutch longitudinal Brain Scale study in which twins, their siblings and their parents were assessed at three year intervals. YC_BS2 took place three years after the baseline (YC_BS1) and targeted 12-year old twins (mean age = 12.2 years, SD = 0.3 years) born between 1995 and 1996 and their 9-18 year old siblings (mean age = 14.8 years, SD = 1.3 years) born between 1990 and 1997. The main aim of the Brain Scale project was to explore to what extent genetic and environmental factors explain individual differences in brain development and cognition. Data collection included psychometric IQ tests, a comprehensive neuropsychological testing protocol, and parental and self-ratings of behavioral and emotional problems. Physical maturation was measured through assessment of Tanner stages. Hormonal levels (cortisol, luteinizing hormone, follicle-stimulating hormone, testosterone, and estrogens) were assessed in urine and saliva. Brain scans were acquired using 1.5 Tesla Magnetic Resonance Imaging (MRI), which provided volumetric measures and measures of cortical thickness. Buccal swabs were collected for DNA isolation for future candidate gene and genome-wide analysis studies.

YE_FITNSS Wave

Wave alternate title	Determinants of adolescent exercise behavior - the psychological response to exercise YE_FITNSS
Short description of the wave	The YE_FITNSS project aimed to investigate determinants of adolescent exercise behavior in a sample of healthy 16-18 year old twins born between 1993 and 1999 (mean age = 17.1 years, SD = .67 years) and their 12-25 year old siblings born between 1988 and 2000 (mean age = 17.2 years, SD = 3.24 years). Body composition was measured, as well as physical fitness (standing jump, hand grip, sit-and reach flexibility, balance tests). Impulsiveness of the subjects was assessed by the delay discounting questionnaire. Regular voluntary exercise behavior was measured by a short lifestyle interview. While being equipped with a VU University Ambulatory Monitoring System (VU-AMS) and Cosmed device, the subjects performed two submaximal exercise tests and one maximal exercise test. The VU-AMS device records electrocardiogram (ECG) data and impedance cardiogram (ICG) data. The Cosmed device measures oxygen consumption (VO2) and carbon dioxide production (VCO2). VO2max (endurance capacity) was derived during the maximal exercise test. Before, during and after the exercise tests, subjects filled out the Activation-Deactivation Adjective Checklist (AD ACL), Feeling Scale (FS) and the Borg’s Rating of Perceived Exertion (RPE) at multiple time points. These questionnaires determined the subjects’ affective response to exercise. DNA was collected through buccal swabs to determine zygosity.

notes	Sleep and sleep habits comprises questions about the amount of sleep and sleeping habits, such as "How many hours a night do you sleep on average during a school week/working week?", "How much does your twin sleep?", and "Do/did the twins sleep together in the same room?"

The NTR was established in 1987 and has enrolled around 120.000 twins and a roughly equal number of their relatives. The majority of twin families have participated one or more times in survey studies on a host of epidemiological variables including social demography, personality, lifestyle, somatic and mental health, and subsamples took part in biomaterial collection (e.g. DNA) and dedicated projects for e.g. neuropsychological, biomarker, and behavioral traits. The recruitment into the NTR is fully inclusive without any restrictions on enrolment. The NTR is committed to actively seek the commitment of its participants to science and their continued involvement in NTR research by maintaining a website, electronic newsletters, and the MijnNTR portal that provides personalized feedback to participants. The NTR resources, e.g. the longitudinal phenotyping, the extended pedigree structures, and the multi-generation genotyping allow for future twin-family research that will contribute to gene discovery, causality modelling, and studies of genetic and cultural inheritance of behavioral traits and mental and physical health. In the CID data catalogue, only the NTR projects for children and adolescents (<18 years of age) have been included.

The main aim of the Brain Scale project was to explore to what extent genetic and environmental factors explain individual differences in brain development and cognition. Data collection included psychometric IQ tests, a comprehensive neuropsychological testing protocol, and parental and self-ratings of behavioral and emotional problems. Physical maturation was measured through assessment of Tanner stages. Hormonal levels (cortisol, luteinizing hormone, follicle-stimulating hormone, testosterone, and estrogens) were assessed in urine and saliva.

Body composition was measured, as well as physical fitness (standing jump, hand grip, sit-and reach flexibility, balance tests). Impulsiveness of the subjects was assessed by the delay discounting questionnaire. Regular voluntary exercise behavior was measured by a short lifestyle interview. While being equipped with a VU University Ambulatory Monitoring System (VU-AMS) and Cosmed device, the subjects performed two submaximal exercise tests and one maximal exercise test. The VU-AMS device records electrocardiogram (ECG) data and impedance cardiogram (ICG) data. The Cosmed device measures oxygen consumption (VO2) and carbon dioxide production (VCO2). VO2max (endurance capacity) was derived during the maximal exercise test. Before, during and after the exercise tests, subjects filled out the Activation-Deactivation Adjective Checklist (AD ACL), Feeling Scale (FS) and the Borg’s Rating of Perceived Exertion (RPE) at multiple time points. These questionnaires determined the subjects’ affective response to exercise.
