Prevalence of mental health diagnoses

Prevalence of mental health diagnoses is defined as the number of participants in the sample diagnosed with a mental health disorder by a clinician according to their medical record out of the total sample. This will be determined by a diagnosis of any of the following in a clinical encounter, problem list, and/or past medical history: * Depression * Anxiety * Mood disorder NOS * Psychotic disorder * Attention-deficit/hyperactivity disorder (ADHD) * Autistic disorder

Time frame: From study start until condition observed, up to 15 years

Cardiometabolic diagnoses - prevalence of obesity

Prevalence of obesity is defined as the number of participants in the sample with obesity in their medical record out of the total sample. Obesity in pediatric populations is determined using BMI-for-age and obesity in adult populations is determined using BMI. BMI is calculated as the weight in kilograms divided by the height in meters squared. Participants will be considered to have obesity if: * There is a diagnosis of obesity in the medical record in a clinical encounter, problem list, and/or past medical history * For children 17 years and younger: there is an available growth chart/height/weight/other data necessary to calculate the BMI-for-age and the BMI-for-age is at or above the 95th percentile * For adults 18 years and older: there is a BMI at or above 30 kg/m2 or the data necessary to calculate BMI and it is at or above 30 kg/m2

Time frame: From study start until condition observed, up to 15 years

Cardiometabolic diagnoses - prevalence of dyslipidemia

Prevalence of metabolic syndrome is defined as the number of participants in the sample with dyslipidemia in their medical record out of the total sample. Dyslipidemia will be defined as: * Diagnosis of dyslipidemia, hypertriglyceridemia, hypercholesterolemia in a clinical encounter, problem list, and/or past medical history * Laboratory evidence of elevated total cholesterol, LDL, triglycerides, and/or low HDL for sex and age

Time frame: From study start until condition observed, up to 15 years

Cardiometabolic diagnoses-prevalence of hypertension

Prevalence of hypertension is defined as the number of participants in the sample with evidence of hypertension in their medical record out of the total sample. Evidence of hypertension includes: * Formal diagnosis of hypertension in a clinical encounter, problem list, and/or past medical history * For children under 13 years old: a blood pressure reading at or above the 95th percentile for age, height, and sex * For children between 13 and 17 years old: a blood pressure reading at or above 130/80 mmHg * For adults 18 years or older: a blood pressure reading at or above 140/90 mmHg

Time frame: From study start until condition observed, up to 15 years

Autoimmune diagnoses - prevalence of hypothyroidism and of hyperthyroidism

Prevalence of hypothyroidism is defined as the number of participants in the sample with evidence of hypertension in their medical record out of the total sample.

Time frame: From study start until condition observed, up to 15 years

Autoimmune diagnoses - prevalence of diabetes

Prevalence of diabetes is defined as the number of participants in the sample with evidence of hypertension in their medical record out of the total sample. Both type 1 and type 2 are included.

Time frame: From study start until condition observed, up to 15 years
