# Minimum longitudinal data This page has been last updated for R11. ### Sandbox directory The minimum longitudinal data file is available as a separate file in the following Sandbox directory: `/finngen/library-red/finngen_R[RELEASE]/phenotype_1.0/` ### Data files This data is available in the following file: `data/finngen_R{RELEASE]_minimum_longitudinal_1.0.txt.gz` Arctic, Eastern Finland and THL biobanks have provided this data. The file contains the following columns:
ColumnDescription
SAMPLE_AGE_1 - SAMPLE_AGE_2Age at DNA sample collection (years), 2 observations
SEXGender (male/female/NA)
HEIGHT_1 - HEIGHT_7Height (cm), 7 observations
HEIGHT_1_AGE - HEIGHT_7_AGEAge at height measurement (years), 7 observations
WEIGHT_1 - WEIGHT_18Weight (kg), 18 observations
WEIGHT_1_AGE - WEIGHT_18_AGEAge at weight measurement (years), 18 observations
SMOKE2_1 - SMOKE2_2Smoking status 2-categories (yes/no) , 2 observations
SMOKE3_1 - SMOKE3_2Smoking status 3-categories (current/former/never), 2 observations
SMOKE5_1 - SMOKE5_2Smoking status 5-categories (current/occasional/quitter/former/never) , 2 observations
SMOKE_1_AGE - SMOKE_2_AGEAge at the moment of the smoking survey (years) , 2 observations
The data contains multiple observations of the same variables as in the [minimum extended phenotype data](/finngen-data-specifics/red-library-data-individual-level-data/what-phenotype-files-are-available-in-sandbox-1/minumum-extended-phenotype-data.md) file *(age, sex, height, weight, smoking, and date variables*). DNA samples have been collected at one or two different dates as well as smoking information. Every individual has at least one DNA sample date. Few individuals might have more than 30 observations from height and weight variables but the vast majority have less than seven observations from height and less than 18 from weight so those amounts have been chosen for height and weight observations in the final data file. If a biobank does not know the exact date for the DNA sample, they have been instructed to estimate the DNA sample date from the age variable. If the day is missing from the DNA sample date, it is estimated as `15.mm.yyyy`. If also the month is missing, though en the DNA sample date is estimated as`30.06.yyyy.` The sample age is calculated from the DNA sample date and birthday. Biobanks have reported height date, weight date and smoking date for each observation. The observations can have different time periods between each other ranging from days to years between observations. The age and sex sent by biobanks have been compared with the values from the DNA sample date and personal identity code. If these values differ then clarification has been requested from the biobank. Other QC checks have also been done. For example, a BMI needs to be between 10-80 $$kg/m^2$$ when checking height and weight, and dates cannot be from the future. Biobanks have been asked to provide all available information about smoking. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
