BACKGROUND: Accurate estimation of food portion sizes remains an important challenge in dietary data collection. The present study aimed to develop a food atlas with adequate visual reference to improve the accuracy of dietary surveys in China. METHODS: A food atlas for dietary surveys in China was developed using three visual reference systems, namely, regularly placed food portions, the two-dimensional background coordinates and common objects known in daily life. The atlas was validated by estimating a meal before and after using the food atlas, and differences in weight estimation were compared using a paired t-test. In total, 50 college students participated in the study. RESULTS: After determination of food varieties; design of the food display; purchase, processing, cooking and weighing of food; photographing food; post-image processing and data processing, a total of 799 pictures of 303 types of food and two types of tableware were produced. The mean value of food weight estimated with the atlas was closer to the actual weight, and the variation range of these values was smaller and more stable than that estimated without the atlas. The differences estimated before and after using the atlas for all foods were significant (P < 0.05). Comparing the differences in weight before using the atlas, the error ranges of food samples were reduced. CONCLUSIONS: A food atlas has been developed for a retrospective dietary survey in China, which can be used to enable a better understanding of nutritional adequacy in the Chinese population.

The aim of this study was to evaluate the effectiveness of preventing mother to child syphilis transmission to improve pregnancy outcomes. We performed a retrospective analysis of municipal databases of mother-to-child syphilis transmission. Pregnant women with syphilis were included. Group specific pregnancy outcomes were analyzed according to treatment. A total of 28 pregnant women were diagnosed with syphilis in 2012; 321 were diagnosed with syphilis in 2018. A prevalence of 0.14% was observed amongst pregnant women in Suzhou city from 2012-2018. Primary treatments included benzathine penicillin, ceftriaxone sodium or erythromycin when patients were allergic to Benzathine penicillin. The treatment coverage was 81.57%, and only 52.86% of pregnant women were adequately treated. Adverse pregnant outcomes were higher amongst untreated women. Expanding early screening coverage and promoting treatment were key to improving pregnancy outcomes amongst women with syphilis.
