Objective To investigate the current situation of maternal self- efficacy of breastfeeding and explore its influencing factors in Zhengzhou. Methods Using the general condition questionnaires, breast feeding self-efficacy scale, perceived social support scale and Edinburgh postnatal depression scale to assess the situation of 180 puerperas by the convenience sampling in one obstetric hospital of Zhengzhou. Results The total score of maternal breast feeding self-efficacy was(114.04 ± 21.57)points.The frequency of delivery, the way of delivery and feeding ways, the average income of family were effected with breastfeeding self-efficacy. The total score of social support was(68.87 ± 10.43) points, the total score of puerperas depression was(7.61 ± 4.25) points.The social support score had positive correlation with breastfeeding self-efficacy(r=0.423, P<0.01). Puerperas depression had negative correlation with breastfeeding self- efficacy(r=- 0.342, P<0.01). Conclusions The maternal breastfeeding level in Zhengzhou was at a lower level. The level of maternal breastfeeding self-efficacy scale was impacted by maternal social support degree, the degree of depression. Measures should be taken to enhance maternal social support degree, reduce the degree of depression, in order to improve the level of maternal breastfeeding self-efficacy.

Objective:To explore the correlation between fluoride intake and serum alkaline phosphatase (ALP) in pregnant women of different gestational periods in endemic fluorosis area.Methods:Pregnant women in Rencheng District, Jinxiang County, Jiaxiang County of Jining City and Yuncheng County of Heze City were selected in April 2020. According to the gestational weeks, pregnant women were divided into early pregnancy group (0 - 12 weeks), middle pregnancy group (13 - 27 weeks) and late pregnancy group (> 27 weeks). The levels of urinary fluoride, ALP, osteocalcin (BGP), C-terminal peptide of β-Ⅰ collagen (β-CTX) and N-terminal propeptide of type Ⅰ collagen (PINP) of pregnant women in each group were measured, and the correlation between urinary fluoride and ALP, BGP, β-CTX, and PINP in pregnant women of different gestational periods was analyzed.Results:A total of 372 pregnant women were selected, including 97 cases in early pregnancy group, 169 cases in middle pregnancy group and 106 cases in late pregnancy group. There was no significant difference in urinary fluoride level between the three groups [(1.20 ± 0.25), (1.23 ± 0.19), (1.24 ± 0.30) mg/L, P > 0.05]. There was significant difference in serum ALP among the three groups ( P < 0.05), among them, the ALP level in early pregnancy was significantly lower than those of middle pregnancy group and late pregnancy group ( P < 0.05), and the ALP level in middle pregnancy was significantly lower than that of late pregnancy group ( P < 0.05). There was no significant differences in serum β-CTX among the three groups ( P > 0.05). There were significant differences in serum BGP and PINP levels among the three groups ( P < 0.05). The serum BGP and PINP levels in late pregnancy group were significantly higher than those of early pregnancy group and middle pregnancy group ( P < 0.05), and there were no significant differences in serum BGP and PINP levels between early pregnancy group and middle pregnancy group ( P < 0.05). There was a significant positive correlation between urinary fluoride and ALP in early pregnancy group ( r = 0.364, P < 0.05), but no significant correlation between urinary fluoride and BGP, β-CTX and PINP ( r = 0.164, 0.117, 0.136, P > 0.05). There was a significant positive correlation between urinary fluoride level and ALP in middle pregnancy group ( r = 0.417, P < 0.05), but no significant correlation between urinary fluoride level and BGP, β-CTX and PINP ( r = 0.127, 0.108, 0.129, P > 0.05). There was no significant correlation between urinary fluoride level and ALP, BGP, β-CTX and PINP in late pregnancy group ( r = 0.179, 0.158, 0.184, 0.149, P > 0.05). Conclusions:The urinary fluoride level of pregnant women in endemic fluorosis area is relatively stable in gestational period. The urinary fluoride level affects the ALP secretion of pregnant women in early and middle pregnancy. It is still necessary to strengthen the measures of improving water quality and defluoridation to reduce the impact of excessive fluoride intake on pregnancy complications in endemic fluorosis area.
