Association between receipt of nutritional counselling during antenatal care visits and anaemia: A cross-sectional study.

BACKGROUND: Anaemia during pregnancy is associated with premature births, low birth weight and increased susceptibility to infection. Almost one-quarter (24.34%) of Ethiopian pregnant women suffer from anaemia. Nutritional counselling during antenatal care (ANC) visits may encourage pregnant women to take a more iron-rich diet and prevent anaemia. The present study examines the association between nutritional counselling during ANC and anaemia among Ethiopian women. METHODS: This cross-sectional study uses the 2016 Ethiopia Demographic and Health Survey (EDHS) data (n = 4, 384). The outcome of interest was anaemia, measured objectively by blood haemoglobin level. The main independent variable was the receipt of nutritional counselling during ANC visits. Univariate, bivariate and multivariable analyses were performed using SAS, version 9.4 (SAS Institute Inc.). RESULTS: Overall, 25.8% of the participants were anaemic and 65.7% received nutritional counselling during ANC visits. Compared with women who received nutritional counselling during ANC visits, a significantly higher proportion of women who did not receive nutritional counselling were anaemic (23.1% vs. 30.8%; p < 0.001). In the multivariable model, compared with women who received nutritional counselling during their ANC visits, the odds of being anaemic were higher among women who did not receive nutritional counselling during their ANC visits adjusted odds ratio = 1.34 (95% confidence interval = 1.07-1.67; p = 0.010). CONCLUSIONS: In a representative sample of Ethiopian women, exposure to nutritional counselling during ANC visits is associated with a lower likelihood of anaemia, independent of potential confounders. Focused ANC counselling that includes nutritional counselling programs during ANC visits can be an effective strategy to prevent and control anaemia.

Effects of individual and neighborhood socioeconomic status on antiretroviral therapy adherence: The role of adherence self-efficacy.

This study aimed to examine the potential mediation effect of adherence self-efficacy on the associations between individual and neighborhood socioeconomic status and antiretroviral therapy adherence in a sample of 337 people living with HIV in South Carolina, United States. Results showed that there were no direct effects of individual or neighborhood socioeconomic status on antiretroviral therapy adherence, whereas both individual socioeconomic status and neighborhood socioeconomic status were associated with adherence self-efficacy, which in turn were related to antiretroviral therapy adherence. These findings suggest that interventions targeting adherence self-efficacy may improve antiretroviral therapy adherence among people living with HIV with low socioeconomic status or those living in socioeconomically disadvantaged neighborhoods.

Low-power low-voltage current readout circuit for inductively powered implant system.

Low voltage and low power are two key requirements for on-chip realization of wireless power and data telemetry for applications in biomedical sensor instrumentation. Batteryless operation and wireless telemetry facilitate robust, reliable, and longer lifetime of the implant unit. As an ongoing research work, this paper demonstrates a low-power low-voltage sensor readout circuit which could be easily powered up with an inductive link. This paper presents two versions of readout circuits that have been designed and fabricated in bulk complementary metal-oxide semiconductor (CMOS) processes. Either version can detect a sensor current in the range of 0.2 µA to 2 µA and generate square-wave data signal whose frequency is proportional to the sensor current. The first version of the circuit is fabricated in a 0.35-µ m CMOS process and it can generate an amplitude-shift-keying (ASK) signal while consuming 400 µ W of power with a 1.5-V power supply. Measurement results indicate that the ASK chip generates 76 Hz to 500 Hz frequency of a square-wave data signal for the specified sensor current range. The second version of the readout circuit is fabricated in a 0.5-µ m CMOS process and produces a frequency-shift-keying (FSK) signal while consuming 1.675 mW of power with a 2.5-V power supply. The generated data frequency from the FSK chip is 1 kHz and 9 kHz for the lowest and the highest sensor currents, respectively. Measurement results confirm the functionalities of both prototype schemes. The prototype circuit has potential applications in the monitoring of blood glucose level, lactate in the bloodstream, and pH or oxygen in a physiological system/environment.
