- Registration Number
- NCT06160479
- Lead Sponsor

Also, Comparison of calcium level in pregnant women in the third trimester who received and not received calcium during pregnancy.
- Detailed Description
The primary outcome is the incidence of hypocalcemia among pregnant women in the first half of pregnancy. This study also has secondary objectives. The one is associating factors with calcium level. After getting the results of maternal calcium level, the normal calcium level group will be divided into 2 groups for receiving calcium 1 g/day and no receiving calcium supplement. Another with hypocalcemia group will be decided into 2 groups for receiving calcium 1 g/day and 2 g/day. The calcium level was collected again in the third trimester.

- Primary Outcome Measures
Name Time Method The incidence of hypocalcemia in pregnant women at Siriraj Hospital 1.5 year The incidence of hypocalcemia in pregnant women in the first half of pregnancy. Material blood will be taken for calcium level. The hypocalcemia is defined as total calcium level less than 8.5 mg/dl.
- Secondary Outcome Measures
Name Time Method The demographic and pregnant factors are associating with maternal calcium level in the first half of pregnancy assessed by the questionnaire and scrupulous chart review 1.5 year The different characteristics between normal calcium and hypocalcemia group in the first half of pregnancy will be studied.

The calcium level in pregnant women in the third trimester 2 year Comparison of maternal serum calcium level in pregnant women in the third trimester between who receive and do not receive calcium supplement. In the normal calcium level group, pregnant women will be divided into 2 groups: receiving CaCO3 1 g/day and no receiving. In the hypocalcemia group, pregnant women will be divided into 2 groups: receiving CaCO3 1g/day and 2g/day. Maternal blood taking for serum calcium level will be done in all participants. Comparison of maternal calcium level between groups will be reported. Statistical analysis will be used t-test and p-value is less than 0.5.
