Long Lasting Difficulties Questionnaire (LLDQ)

The Long Lasting Difficulties Questionnaire (LLDQ) measures financial, health or social problems in the preceding 12 months. The 12 items are rated on a 5-point Likert scale (0 = no, 1 = slight, 2 = moderate, 3 = serious, NA = n.a) and include difficulties with family members (including the partner), friends, people in the neighbourhood, difficulties at school/work, and the occurrence of sexual, financial, or housing problems.

Purpose	The purposes of the Generation R study are to (1) describe normal and abnormal growth, development and health from early fetal life to adulthood in a multi-ethnic population; (2) identify (epi-)genetic, biological, social and environmental determinants of this normal and abnormal growth, development and health; and (3) contribute to the development of strategies for optimizing health and healthcare for pregnant women and children.

Description	The Generation R Study is a population-based prospective cohort study from fetal life until adulthood. The study is designed to identify early environmental and genetic pathways leading to normal and abnormal growth, development and health. An important focus of Generation R is to identify early life determinants of common (mostly non-communicable) diseases in adulthood. Pregnant women living in the Rotterdam area, the Netherlands, were included between 2002 and 2006. After birth, the children and their parents have been followed in multiple assessment waves up until young adulthood.
Purpose	The purposes of the Generation R study are to (1) describe normal and abnormal growth, development and health from early fetal life to adulthood in a multi-ethnic population; (2) identify (epi-)genetic, biological, social and environmental determinants of this normal and abnormal growth, development and health; and (3) contribute to the development of strategies for optimizing health and healthcare for pregnant women and children.

Alternate title	Gen-R Next, GenR Next
Description	Generation R Next is a population-based prospective cohort study from preconception onwards in Rotterdam, the Netherlands. The Generation R Next Study is designed to identify periconceptional environmental and health determinants that influence embryonic and early fetal development, and the consequences early fetal adaptations for the child’s later life health. Women living in the Rotterdam area, the Netherlands, with the wish to conceive or those who were pregnant at the time, were eligible for enrollment between 2017 and 2021. After birth, the children and their parents have been followed up until age 1 years, with the aim to also collect data at later ages in childhood.
