Author (yr) Country (City) Population (n) Design Type of BF intervention Outcome variable Type of analysis Effects & associations Quality assessment
Seijts GH, Yip J. (2008) [50] Canada Alumni of a large Canadian business school, living in Canada at the time of the study (n = 220) Cross-sectional -Support from colleagues Support for BF accommodation in the workplace Pearson correlation
ANOVA
Employees with children reported stronger support for BF accommodations (i.e. lactation space), this was mediated by knowledge Very low
Suyes K, Abrahams SW, Labbok MH (2008) [51] USA (Southeastern) Employees of a corporation that has a reputation of being “family friendly” (n = 407) Cross-sectional -BF education
-Designated spaces for BF or expressing milk
-Flexible scheduling to support milk expression
-Provision of breast pumps
-Support from colleagues
Index of BF Attitudes (IBA) Linear regression Having had a co-worker who BF or expressed milk at work was associated with 2.4 point increase in average IBA score. Having ever breastfed was also positively associated with the score. Low
Zhuang J, Bresnahan M, Zhu Y, Yan XD, Bogdan-Lovis E, Goldbort J, et al. (2018) [52] USA Working adults (males and females) drawn form a representative sample of almost every state (n = 1000, n = 168 women who were BF at the time of the interview) Cross-sectional -Designated spaces for BF or expressing milk
-Provision of breast pumps
-Other
Stigma about BF, intention to help a nursing coworker, self-efficacy of pumping ANOVA, bivariate correlations. HLM and SEM models Behavior intention to help BF coworkers was explained by perception of fairness, coworker support and stigmatization (47% of the variance). “Ick response” was positively associated with stigma, and negatively associated with support and fairness.
Self-efficacy to pump at work. For women still BF, models showed that perceptions of fairness (ß = 0.3) and coworkers’ support (ß = 0.24) were positively associated (relationships were confirmed by the SEM)
