Title: Randomised Controlled Trial to Evaluate the Preventive Effect on Mortality and Serious Morbidity/ Hospitalisations of Daily Vitamin D Supplements in Small for Gestational Age Term Infants
Brief Summary: The purpose of this study is to determine whether a weekly supplement of vitamin D to low birth weight term infants will reduce their mortality and hospital admissions and improve their immunity.


Options:
A: Inclusion Criteria:

* Born at term, as determined from last menstrual period
* Weighing \< 2.5 kg
* Resident within 12 km of the hospital and expected to continue living in the area for the following 6 months
* With no severe congenital abnormalities
* No morbidity severe enough to be expected to result in death before 7 days due to severe respiratory distress, shock, pulmonary sepsis, etc.
* Parental informed consent
B: Inclusion Criteria:

* New pulmonary (including pleural) tuberculosis with/without an extrapulmonary lesion in children age 6 months to 15 years

Exclusion Criteria:

* Weight for height \< 70 % of NCHS median (reason: zinc as per guidelines is given as standard point of care to all severely malnourished children)
* Bilateral pedal oedema
* Known HIV + ve
* Place of residence outside Delhi (including physicians discretion)
* History of previous ATT treatment or INH prophylaxis for more than 48 hours prior to enrollment
* Signs of upper airway obstruction, or an arterial oxygen saturation less than 92% in room air
* Signs of renal, hepatic, or cvs disease
* Unable to attend follow up session for reading of Mantoux tests
* Documented intake of zinc continuously for \> 2 weeks in the preceding 4 weeks at enrollment
* CNS, osteo-articular, pericardial, renal TB
* History of contact with a documented case of drug resistant TB
C: Inclusion Criteria:

* Age 2-17 years
* AD rated 10-72 by EASI scale
* Wintertime onset or exacerbation of AD

Exclusion Criteria:

* Active skin infection
* History of summertime onset or exacerbation of AD
* History of underlying illness causing immunosuppression within the past 2 years (eg. hematologic malignancies)
* Medications causing iatrogenic immunosuppression (eg. cyclosporine; azathioprine, oral steroids) taken within the past month
* Parathyroid disease
* Acute or chronic renal disease
* Hypercalcemia or hypocalcemia
* Thyroid disease
* History of osteomalacia or Paget's disease of bone
* History of malabsorption (eg cystic fibrosis)
* Planned trip to sunny climate during the one-month study
D: Inclusion Criteria:

* Healthy singleton term born infants of appropriate size for gestational age (AGA) according to the Centers for Disease Control growth charts based on weight at birth between the 5th and 95th percentiles for sex; and born to healthy breastfeeding women. This allows us to assess growth and bone mineral accretion without bias of intrauterine growth restriction.

Exclusion Criteria:

* Infants of mothers with history of gestational diabetes or hypertension in pregnancy; chronic alcohol use; malabsorption syndromes due to malabsorption of vitamin D (celiac disease, Crohn's etc.); and multiple births.
* Should any exclusion criteria be identified after recruitment, the infant will be excluded from the main analyzes, but followed in a separate arm as intent-to-treat.
