Urban sprawl is a particular pattern of the street network and land use. The relationship between street networks and sprawl has been discussed by urban scholars in developed and high-income countries. Nevertheless, there is a lack of research on the relationships between street connectivity and urban travel behavior, particularly among emerging markets. This paper aims to study correlations between urban mobility and street-length density as an indicator for assessing the compactness of an area by developing two hierarchical regression models and controlling for socioeconomic variables in two large Pakistani cities: Lahore and Rawalpindi. Moreover, this paper defines optimal cutoff values for street-length density and active transport. Finally, three chi-square tests were conducted to assess the differences between using different mode choices by people living in sprawled neighborhoods versus compact neighborhoods. Our findings confirm the use of different transport modes depending on the purpose of the trip (commuting or non-commuting), length of trip (within or outside the neighborhood), and starting point (sprawled neighborhood or compact area). We also find a positive correlation between street-length density around homes and commuting distance, the frequency of public transport use, and the use of private motor vehicles in commuting trips in the two cities. Street-length density around workplaces is correlated with commuting distance, the frequency of public transport use, and the use of private motor vehicles when socioeconomic variables (including age, daily activity, and monthly income) are controlled for in the two models. The behavior of Pakistani residents changes with a street-length density of 137 and 144.7 m/m2 for homes and workplaces, respectively, in terms of using active mobility.

This paper examines how transport policy measures have influenced travel behaviour to promote sustainable transportation. Data were collected through a survey on 384 vehicle users to represent the 36 sections of Shah Alam, Selangor. This paper also studied the readiness of an urban population to reduce car usage. Maj ority of the respondents stated that the increase in petrol and toll prices would be the key factors to reduce car use, and more provision of public transport would encourage them to use public transport. However, Chi-square test showed that the willingness of the respondents to use public transport has a strong relationship with the frequency of driving a vehicle. The level of willingness to use public transport is lower when a car is used more frequently. Results also suggested that the majority of the respondents were not ready to consider cycling and walking as alternatives.

Introduction. Intense physical activity is associated with good health and wellbeing of an individual, and its manifestations in students can have gender and socio-cultural features. The purpose of the study is to identify the features of physical activity of Russian and foreign students of a regional university through the assessment of its motivators, barriers and interrelation with self-esteem indicators, the knowledge of which can be used as the basis for creating personalized preventive health promotion programs. Materials and Methods. An online survey among 423 Russian and foreign students of a regional university was conducted using the Godin-Shephard Leisure-Time Physical Activity Questionnaire using the Ashton Motivators and Barriers Scale and the modified method of Dembo – Rubinstein. The data obtained were statistically processed with the calculation of Student’s t-test, chi-square, and Pearson’s correlation coefficient. Results. It has been revealed that two-thirds of the respondents have an optimal level of physical activity, and its motivators (the desire to improve health, physical shape, and body) and barriers (lack of time) are universal. Russian female university students surpass foreign ones in terms of the duration of physical activities, and foreign girls are inferior to foreign young men in terms of the frequency of classes. Barriers specific to Russian girls have been identified: Inappropriate weather and the belief that physical activity is not a right occupation for women. Russian young men have mentioned the lack of conditions for training as a barrier. The difference between Russian young men and foreign ones is that foreigners find positive correlation between physical activity, confidence, and physical attractiveness. Discussion and Conclusion. The results obtained may be useful for teaching personnel of university departments of physical education, medical and psychological services, and student self-government organizations. It is recommended that university prevention programs be gender-specific, culturally oriented, aimed at neutralizing the system of internal and social barriers to attending classes, and based on the student's self-esteem potential.

Major Factors

Road fatalities remain a major public health concern as over 1.3 million people across the world die in road accidents annually, and another 20-50 million sustain injuries. Malawi, with vehicle ownership about 437,416, has not been an exception to this, with reported fatality rates of 35 crash deaths per 100,000 population, possibly due to limited understanding of factors that contribute to such high road fatality rates. This may have resulted in implementing inappropriate and ineffective mitigation measures. Thus, the overall objective of this study was to investigate the availability, including their functionality and usage of seatbelts in motor vehicles, which could possibly be one of the major factors for increase in road fatalities. To establish the rates of availability, ncluding their functionality and usage of seatbelts in motor vehicles, primary data through survey for a sample of 1,200 vehicles were investigated. The independent ariables of data were cross tabulated with the dependent variables to establish these rates. Chi-square test was also performed to establish the significance of associations between the cross tabulated variables. The analysis found that Malawi’s drivers and assengers poorly comply with seatbelt laws. The overall seatbelt usage rate was 35.8%. In this regard, where over 90% of motor vehicles in Malawi have functional seatbelts, poor enforcement of existing seatbelt laws and awareness on the dangers of not using eatbelts could account for the low usage.

Object Surgical complications increase the cost of health care worldwide and directly contribute to patient morbidity and mortality. In an effort to mitigate morbidity and incentivize best practices, stakeholders such as health insurers and the US government are linking reimbursement to patient outcomes. In this study the authors analyzed a national database to determine basic metrics of how comorbidities specifically affect the subspecialty of neurosurgery. Methods Data on 1,777,035 patients for the years 2006–2011 were acquired from the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) database. Neurosurgical cases were extracted by querying the data for which the surgical specialty was listed as “neurological surgery.” Univariate statistics were calculated using the chi-square test, and 95% confidence intervals were determined for the resultant risk ratios. A multivariate model was constructed using significant variables from the univariate analysis (p < 0.05) with binary logistic regression. Results Over 38,000 neurosurgical cases were analyzed, with complications occurring in 14.3%. Cranial cases were 2.6 times more likely to have complications than spine cases, and African Americans and Asians/Pacific Islanders were also at higher risk. The most frequent complications were bleeding requiring transfusion (4.5% of patients) and reoperation within 30 days of the initial operation (4.3% of patients), followed by failure to wean from mechanical ventilation postoperatively (2.5%). Significant predictors of complications included preoperative stroke, sepsis, blood transfusion, and chronic steroid use. Conclusions Understanding the landscape of neurosurgical complications will allow better targeting of the most costly and harmful complications of preventive measures. Data from the ACS NSQIP database provide a starting point for developing paradigms of improved care of neurosurgical patients.

The present study aimed to investigate different socioeconomic factors as well as the perceptions and travel behaviors associated with urban sprawl in two cities of different sizes in Iran, as a developing country in the Middle East. Four Weighted Least Squares (WLS) regression models were developed for Hamedan and Nowshahr, as examples of large and small cities in Iran, respectively. The findings showed different correlations related to urban sprawl between Iranian cities and high-income countries in terms of socioeconomic and travel behavior determinants. Urban sprawl around home in Hamedan was positively correlated with the number of cars and driving licenses in households, the use of a private car for trips, and less use of public transport. Urban sprawl around homes in Nowshahr was related to an increased number of cars, the use of private cars for non-commuting trips, less sense of belonging to the neighborhood, and lower income. Additionally, urban sprawl around workplaces was correlated with main daily activity, number of non-commuting trips, mode of choice for non-commuting, and residential location choice in Hamedan a swell as monthly income, daily shopping area, frequency of public transport use, quality of recreational facilities, length of time for living in the current home, and commuting distance in Nowshahr.

ABSTRACT Objective: To verify the prevalence and association of parents’ and children’s anxiety concerning socioeconomic variables and child’s behavior during dental care. Methods: This was a quantitative, observational, transversal and descriptive study. Data collection was performed through a questionnaire aiming at sociodemographic data and dental experience as well as Venham Picture Test, Corah Dental Anxiety Scales and Frankl Anxiety Scale. Data were analyzed using descriptive and inferential statistics (Chi-square and Fisher’s exact test), α = 0.05. Results: The sample consisted of 7 to 9 year- old children (57.9%.), of whom 72.6% were submitted to invasive procedures. The prevalence of anxiety among children was 43.2% (n = 41). Regarding parents / guardians, the prevalence of anxiety was 88.4% (n = 84). A significant association was found between the dental appointment experience and the child’s anxiety (p = 0.050) using the VPT. A significant association between anxiety and the type of dental procedure (p = 0.017) as well as the child’s experience (p = 0.000) using the Frankl scale. Conclusion: There was no association between anxiety and socioeconomic variables. In the variables related to dental experiences, a significant association was found between the experience of the dental appointment and the anxiety of the child using the VPT scale. An association between anxiety and the type of procedure was observed, as well as dental appointment experience, using Frankl scale.

Increased Risk

The proportion of people aged 65 years and older regularly traveling in motor vehicles continues to grow worldwide. In a previous convenience sample, we observed many older people using comfort accessories when traveling in vehicles, and these may contribute to the known increased risk of injury in crashes among older people. In this study, we aimed to estimate population-level use of these devices and examine associations between demographic, health, and travel behavior factors and their use. The point estimate of self-reported use of comfort accessories was 25.7% (95% confidence interval [CI] = [19.6%, 31.9%]). Cushions on the vehicle seat were the most common type used (14.3%, 95% CI = [9.7%, 19.0%]), and increasing age, female gender, and frequent vehicle travel were significantly associated with their use. Less frequently used were seat belt padding (10.5%, 95% CI = [6.3%, 14.6%]) and back/neck supports (6.5%, 95% CI = [2.7%, 10.2%]). Back/neck and multiple area pain were significantly associated with the use of the latter.
