Objective:
A systematic review was conducted to know the contributions of social network analysis (SNA) to public health research (PHR).
Materials And Methods:
The databases analyzed were Academic Search Complete, PubMed and MEDLINE. A total of 1 151 articles were processed, of which 361 met the inclusion criteria and make up the final sample.
Results:
The generic profiles of assessed papers are quantitative (84.5%) and cross-sectional (64.5%), and use conventional statistical procedures to test hypotheses (68.9%). Studies examining the role of networks as a risk factor or health protection (38%), epidemiological research (34.6%), and work analyzing systems that provide social and health care (24.4%) are noteworthy.
Conclusions:
Remarkable differences among research were identified at the egocentric and sociocentric levels of analysis. Results are discussed in order to increase the effectiveness of PHR through SNA methods.
