OBJECTIVE: This systematic review aims to gather and appraise existing evidence on the associations between serum vitamin D concentrations during pregnancy and at birth and the development of eczema, wheezing, and RTIs in infants.
DATA SOURCES: PubMed, MEDLINE, ProQuest, Scopus, CINAHL, Cochrane Library and Academic Search Premier databases were searched systematically using specified search terms and keywords.
STUDY SELECTION: Articles on the associations between serum vitamin D concentrations during pregnancy and at birth and eczema, wheezing, and RTIs among infants (1-year-old and younger) published up to 31 March 2019 were identified, screened and retrieved.
RESULTS: From the initial 2678 articles screened, ten met the inclusion criteria and were included in the final analysis. There were mixed and conflicting results with regards to the relationship between maternal and cord blood vitamin D concentrations and the three health outcomes-eczema, wheezing and RTIs-in infants.
CONCLUSION: Current findings revealed no robust and consistent associations between vitamin D status in early life and the risk of developing eczema, wheezing and RTIs in infants. PROSPERO registration no. CRD42018093039.
MATERIALS AND METHODS: The method used was a cross-sectional study. Self-administered knowledge, attitude, and practice questionnaires were distributed among childbearing women attending Maternal & Child Health Clinics in the East Coast region of Malaysia.
RESULTS: The findings revealed that most respondents (N = 896) had good or moderate knowledge (80.1%) and attitudes (77.3%) regarding PFMT but most of them (87.2%) still lacked practice. However, there was no association between urinary incontinence and PFMT practice. On the contrary, married women showed a higher risk of urinary incontinence.
CONCLUSIONS: The practice of pelvic floor muscle training should be recommended and emphasized to childbearing women by healthcare professionals.
