Serum Folic Acid Status, Genotyping MTHFR 677C-->T of the Mother and Serum Folic Acid Status, DNA Methylation of IGF2 Gene of the Children: East Jakarta Cohort Study

This study is part of the East Jakarta Cohort Study to assess the current micronutrient status of the mothers and their children. The study also includes the assessment of genotyping of MTHFR 677C-->T of the mother and DNA methylation of IGF2 gene of the children.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

The initial study recruited 315 mothers in the public health centre and one district hospital in East Jakarta. The follow-up study is able to re-visit the 127 of them. This also includes 127 peers of the subject that lives in the same neighbourhood. The design of the study is case-cohort design, part study of the existing cohort. The assessment of the follow-up study includes the mother and the children born in the initial study. Anthropometric measurement, socioeconomic data from a structured questionnaire, biomarker assessment, blood pressure were obtained from the subjects.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

3 years to 40 years (Child, Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

In 2014, the pregnant mothers in 10 public health centre and one sub-district hospital in East Jakarta were recruited in the study. They were in the third trimester gestation period, receive iron-folic acid supplementation and ANC. In 2018, the repeated collection was conducted to collect follow-up data. We also include peer of the subjects that lived in the same neighbourhood since the first cohort study and have children in the same age with cohort participant

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
East Jakarta Cohort Study
One group included in the study was originated from mothers who participated in the first data collection pregnancy. The follow-up study included mothers and their children born as the subject in the follow-up in the study. This study also includes peer of the subjects that lived in the same neighbourhood since the first cohort study and have children in the same age with cohort participant

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Serum folic acid status
Time Frame: December 2018 - March 2019
The measurement of serum folic acid status is using LC-MS/MS

December 2018 - March 2019

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Serum Homocysteine
Time Frame: December 2018-March 2019

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures.
