The Prevalence of Sub Clinical Hypothyroidism During Early Pregnancy in Pakistan (PRECIOUS)

March 13, 2018 updated by: Abbott
The Precious study is likely to help determine the frequency (percentage) of subclinical hypothyroidism among pregnant women in Pakistan It will also help to determine the risk factors for developing subclinical hypothyroidism during pregnancy

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

18 years to 45 years (ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

Design Details

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
Frequency of subclinical hypothyroidism in pregnant females
Time Frame: 12 months
Continuous variables with normal and non-normal distributions would be reported as mean (SD) and median [inter-quartile range (IQR)], respectively. Prevalence of subclinical hypothyroidism with 95% confidence Interval (CI) will be calculated. Continuous variables between group will compared by using Independent sample t test, and categorical variables will compare by using the chi-square test.
12 months

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
The risk factors that might be associated with subclinical hypothyroidism in all enrolled pregnant patients.
Time Frame: 12 months
Odds Ratios (OR) and their 95% Confidence Intervals (CI) will be estimated using Logistic Regression. The likelihood ratio test used to assess the association between the explanatory variables and the risk of the subclinical hypothyroidism. Univariable analyses will perform to examine the effect of each variable on the risk of subclinical hypothyroidism. In multivariate analysis all insignificant variables (p >0.05) will check for their confounding and interaction effects before their removal from the final model.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (ACTUAL)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 1, 2017

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. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
January 1, 2018

Study Completion (ACTUAL)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
