Oral Glucose Tolerance Datasets

Description

Data obects containing results from stanadard 75g OGTT including glucose, insulin and demographic data.

All OGTT studies were done after an overnight fast, and all glucose results are plasma glucose (mg/dL) measured on a YSI instrumement (glucose oxidase). Plasma Insulin (mU/L or uU/mL). All OGTTs were dones prior to any intervention (ie, participants were not on study medications).

Usage

ogtt_wide

ogtt_nested

Format

ogtt_wide A dataframe with 184 OGTT results contains glucose and insulin in wide format with time noted in the variable name (e.g., glucose_000, glucose_030). ogtt_nested contains time, glucose, and insulin in long format a dataframe stored in a list-column for each participant. Demographic data includes:

age

Age, years

gender.f

Gender, factored as Male/Female

race.f

Race, factored using self-reported classification]

height_cm

Height, cm

weight_kg

Weight, kg

bmi

Body mass index (BMI, kg/m^2)

hdl_bl, dld_bl, trigs_bl

Fasting lipids: LDL and HDL cholesterol, Triglycerides (mg/dL)

⁠glucose_***⁠

Plasma Glucose (mg/dL), with time in minutes

⁠insulin_***⁠

Plasma Insulin (uU/mL), with time in minutes

ogtt_df

A nested dataframe with a single OGTT result per row in the nested dataset (ogtt_nested), Time points, in minutes (0, 30, 60, 90, 120) denoted either in the variable name (⁠_000⁠, ⁠_030⁠) or in the time column of the nested dataset

'ogtt_wide' A dataframe with 184 OGTT results, with a nested dataframe with each participant result (time, glucose, insulin)
