General characteristics of the participants
Table 1 shows the general characteristics of the study participants. Overall, a total of 875 participants with a mean age of 26.2 ± 5.9 were enrolled in the study. Of all the participants, 491 (56.1%) were aged 25 years or older, 611 (69.8%) were of the Basoga ethnic group, 388 (44.3%) had secondary education as their highest level of education, 437 (49.9%) had no employment, 710 (81.1%) were married, 637 (75.4%) were Catholic, and 80 (9.1%) were mothers living with HIV. The majority of the participants had attended less than four antenatal care visits at the most recent pregnancy (651 or 74.4%), 227 (25.9%) had a baby with a second birth order, 727 (83.1%) had delivered in a health facility, 346 (39.4%) lived in a rural area, 654 (74.7%) knew that pre-lacteal feeding could cause diarrhoea, while 611 (69.8%) reported that pre-lacteal feeding could cause difficulties in breathing. Furthermore, the majority of the participants attended postnatal care at a general hospital (507 or 57.9%) and public health facility (675 or 77.1%). 510 (58.3%) travelled less or equals to 5 km from their place of residence to the health facility for postnatal care services. The mean distance travelled was 7.0 ± 8.2 km.
Pre-lacteal feeding and the relationship with personal and health services related factors
Table 2 summarizes the results for the comparison of differences in pre-lacteal feeding with personal and health service-related factors. Our data show that 319 (36.5%) participants practiced pre-lacteal feeding. Participants who practiced pre-lacteal feeding were on average similar to those who never practiced pre-lacteal feeding: 26.4 ± 6.2 versus 26.1 ± 5.7 years, p = 0.491. Pre-lacteal feeding was more common among participants aged 25 years and beyond (57.1%), the Basoga ethnic tribe (64.9%), those with a secondary level of education (43.9%), the self-employed (43.9%), the married (74.3%), and those living with HIV (90.0%).
Participants who attended less than four antenatal care visits at the most recent pregnancy (79.9%), gave birth to the second child (23.8%), delivered in a health facility (73.4%), and resided in a rural setting (40.1%) had a higher prevalence of pre-lacteal feeding. The distribution of pre-lacteal feeding by knowledge of risks of diarrhoea and breathing difficulties, place of antenatal and postnatal care attendances, and travel distance is equally shown in Table 2. We observed statistically significant differences in pre-lacteal feeding concerning the type of employment (p = 0.003), marital status (p < 0.001), number of antenatal care visits at the most recent delivery (p = 0.005), mode of delivery (p = 0.022), place of delivery (p < 0.001), knowledge of whether pre-lacteal feeding causes breathing difficulties or not (p < 0.001), place of recent attendance of antenatal care (p < 0.001), and distance travelled from place of residence to a health facility for postnatal care (p < 0.001).
Factors associated with pre-lacteal feeding at unadjusted and adjusted analysis
In the unadjusted analysis (Table 3), pre-lacteal feeding was less likely when the participant was unemployed (PRR 0.72; 95% CI 0.55–0.93), married (PRR 0.65; 95% CI 0.53–0.79), had attended four or more antenatal care visits at the most recent pregnancy (PRR 0.73; 95% CI 0.58–0.92), had received health education on infant feeding practices during antenatal care visits (PRR 0.53; 95% CI 0.45,0.63), had a spontaneous vaginal delivery (PRR, 0.56; 95% CI, 0.47–0.67), had delivered in a health facility (PRR 0.56; 95% CI 0.47–0.67), had given birth to a new born that had a birth weight of 2.5-5.0 kilograms (PRR, 0.68; 95% CI, 0.50–0.92), knew that pre-lacteal feeding could cause breathing difficulties (PRR 0.65, 95% CI 0.52–0.81), had given the baby colostrum (PRR, 0.50; 95% CI, 0.40–0.61), and had attended postnatal care at a general hospital (PRR 0.84; 95% CI 0.70–0.99). However, recent attendance of antenatal care at a public health facility (PRR 2.85; 95% CI 2.03–4.02) and travel distance of 5 km and beyond to access postnatal care services (PRR, 1.46; 95% CI, 1.23–1.74) was associate with a higher likelihood of pre-lacteal feeding.
In the adjusted analysis (Table 3), the number of antenatal care visits at the most recent pregnancy, birth weight, receipt of colostrum, and the level of health facility did not improve the model fitness so they were dropped. Our final model was parsimoniously characterized by the following: the lowest Akaike Information Criteria (AIC) of 1207.2, a goodness-of-fit value of 533.9 (Chi-square = 864, p = 1.000), and a statistically insignificant p-value associated with a linktest (p = 0.807).
In the adjusted analysis, our data show that pre-lacteal feeding was less likely among unemployed participants (aPRR, 0.70; 95% CI, 0.50–0.91), married (aPRR, 0.71; 95% CI, 0.58–0.87), had received health education on infant feeding at the most recent pregnancy (aPRR, 0.72; 95% CI, 0.60–0.86), had a spontaneous vaginal delivery (aPRR, 0.76; 95% CI, 0.61–0.95), had delivered outside a health facility (aPRR, 0.73; 95% CI, 0.60–0.89), and knew that pre-lacteal feeding could lead to difficulties in breathing (aPRR, 0.70; 95% CI, 0.57–0.86). Conversely, pre-lacteal feeding was more likely among mothers who attended antenatal care services at public health facilities compared to those who attended recent antenatal care services at a private-not-for profit health facility (aPRR, 2.41; 95% CI, 1.71–3.39), and among participants who travelled 5 km and beyond to receive postnatal care services compared to those who travelled less or equals to 5 km (aPRR, 1.46; 95% CI, 1.23–1.72).
