The relationship between parental religiosity and school age children's dietary behavior in Ningxia Province, China: A cross-sectional study.

BACKGROUND: Studies have shown parental religious involvement was associated with better health behaviors of their children. However, the relationship between parental religiosity and child dietary behaviors remains unclear. OBJECTIVES: This study aimed to examine the relationship between parental religious involvement and the dietary behaviors of school-aged children in mainland, China. METHODS: Participants were selected from a northwest province of China using a multi-stage sampling process from July 2017 to October 2017. The frequency of parental religious activities and the importance of religion in life, along with the dietary behaviors of children, were collected using a questionnaire. Dietary pattern analysis coupled with multivariable linear regression was employed to test the association between parental religious involvement and children's dietary behavior. RESULTS: The regression model indicated no significant relationship between parental religious behaviors and children's dietary behaviors in the overall sample. However, the frequency of mother's religious attendance was inversely related to children's consumption of vegetables (ß = -0.40, P < 0.05) in the Hui subsample (vs. Han) when stratifying analyses by ethnicity. CONCLUSION: These findings suggest among those of Hui ethnicity, parental religious involvement may impact children's dietary behavior in a way that may affect their future health habits.

Flexible and Electroactive Textile Actuator Enabled by PEDOT:PSS/MOF-Derivative Electrode Ink.

Smart fabrics that integrate electronic devices with textiles are emerging as potential candidate for apparel and electronics industries. Soft actuators based on conducting polymers are promising for smart fabrics because of light weight, flexibility, and large deformation under low voltage. However, due to the distinct characteristics of textile and electronic components, the connection between textiles and electronic devices still keeps a challenge in development of smart fabrics. Here, we report an new strategy to prepare a flexible and electroactive textile actuator. The fabric electrolyte was directly coated with an electrode ink, which is composed of Poly(3,4-ethylenedioxythiophene):poly(styrene sulfonic acid) doped with carbonized carbon nanotubes wired zeolite imidazolate framework-8 composite. A pre-treatment of the fabric was made by soaking hydrophobic poly(vinylidene fluoride-co-hexafluoropropylene) to increase the ionic conductivity (6.72 mS cm-1) and prevent the electrode ink from penetrating through the fabric. It was found that the textile actuator could work in air stably under a low voltage of 3 V and operate at frequencies from 0.1 to 10 Hz with large strain difference (0.28% at 0.1 Hz), fast strain rate (2.8% s-1 at 10 Hz) and good blocking force (0.62 mN at 0.1 Hz). The key to high performance originates from high ionic conductivity of fabric electrolyte and large specific surface area, good mechanical properties of the metal-organic framework derivative-based composite electrodes, which present insights into preparing other smart fabrics such as textiles sensors, flexible displays, and textile energy storage devices.
