To investigate the association between the weight status of first-year female
students (FYFS) and various weight management-related characteristics to identify
possible components of a weight management programme for students. Mean (^standard deviation (SD)) body mass index (BMI) of the FYFS was
21.8 ^ 2.6 kg m22
, with 7.2% being underweight, 81.9% normal-weight, 10.0%
overweight and 0.8% obese. Underweight, normal-weight and overweight students
differed with regard to their perception of their weight (P , 0.001), weight goals
(P , 0.001) and previous weight-loss practices (P , 0.001). Mean ^ SD score on the
26-item Eating Attitudes Test (EAT-26) was 8.5 ^ 9.0 with 8.4% classified as high
scorers. Mean ^ SD score on the 34-item Body Shape Questionnaire (BSQ) was
87.7 ^ 32.2, with 76.1% classified as low, 11.9% as medium and 11.9% as high scorers.
The self-concept questionnaire indicated that 36.7% had a high, 43.9% a medium and
19.4% a low self-concept. Higher BMI correlated with a higher BSQ score (P , 0.001),
a lower self-concept (P ¼ 0.029) and a higher EAT-26 score (P , 0.001). Smoking was
prevalent amongst 13.1% of students, and 51.2% used vitamin and/or mineral
supplements. Students who quitted smoking had higher (P ¼ 0.006) BMI
(22.7 ^ 2.9 kg m22
) than those who never smoked before (21.6 ^ 2.5 kg m22
).

Onyango, Elizabeth Opiyo; Crush, Jonathan S.; Owuor, Samuel
The current study focuses on food consumption and dietary diversity among internal
migrant households in Kenya using data from a city-wide household survey of Nairobi conducted
in 2018. The paper examined whether migrant households are more likely to experience inferior
diets, low dietary diversity, and increased dietary deprivation than their local counterparts. Second,
it assesses whether some migrant households experience greater dietary deprivation than others.
Third, it analyses whether rural-urban links play a role in boosting dietary diversity among migrant
households. Length of stay in the city, the strength of rural-urban links, and food transfers do not
show a significant relationship with greater dietary diversity. Better predictors of whether a household
is able to escape dietary deprivation include education, employment, and household income. Food
price increases also decrease dietary diversity as migrant households adjust their purchasing and
consumption patterns.

Metabolic Age (MetAge) and body composition analysis may reflect an individual’s metabolic status, which is believed to influence male sexual and gonadal functions. Although erectile dysfunction (ED) and hypogonadism are increasingly prevalent with age, they are also detected among younger men. This study aims to assess the impact of MetAge and body composition on male sexual and gonadal status overall, and particularly in men younger than 40 years of age.

Remote robotic surgery is one of the most interesting Tactile Internet (TI) applications. It has a huge potential to deliver healthcare services to remote locations. Moreover, it provides better precision and accuracy to diagnose and operate on patients. Remote robotic surgery requires ultra-low latency and ultra-high reliability. The aforementioned stringent requirements do not apply for all the multimodal data traffic (i.e., audio, video, and haptic) triggered during a surgery session. Hence, customizing resource allocation policies according to the different quality-of-service (QoS) requirements is crucial in order to achieve a cost-effective deployment of such system. In this paper, we focus on resource allocation in a softwarized 5G-enabled TI remote robotic surgery system through the use of Network Functions Virtualization (NFV). Specifically, this work is devoted to the joint placement and scheduling of application components in an NFV-based remote robotic surgery system, while considering haptic and video data. The problem is formulated as an integer linear program (ILP). Due to its complexity, we propose a greedy algorithm to solve the developed ILP in a computationally efficient manner. The simulation results show that our proposed algorithm is close to optimal and outperforms the benchmark solutions in terms of cost and admission rate. Furthermore, our results demonstrate that splitting application traffic to multiple VNF-forwarding graphs (VNF-FGs) with different QoS requirements achieves a significant gain in terms of cost and admission rate compared to modeling the whole application traffic with one VNF-FG having the most stringent requirements.
