Differences in Adolescent Effective Contraception Use between Population Densities

Undesired pregnancy is a particular problem in the adolescent population. Close to 90% of the pregnancies in this population are unintended and account for significant economic and health burdens. Studies addressing effective contraceptive use by population density are lacking. In this paper, the authors hypothesize that contraception counseling and effective contraception use varied by population density. 

This was a cross-sectional study using the 2006-2010 National Survey of Family Growth data, including female subjects aged 15 to 19. The primary exposure was population density, defined as Principal city of a Metropolitan Statistical Area (MSA) or “city”, Other MSA or “non-city urban”, and Not MSA or “rural.” The primary outcome was effective contraception use and the secondary outcome was contraceptive counseling exposure. Multivariate analysis using logistic regression was performed to estimate the association between population density and effective contraception use, as well as the likelihood of receiving contraceptive counseling. 

There were 2284 females aged 15 - 19 included for analysis, with a mean age of 17. Compared to non-city urban dwellers, city adolescents had similar effective contraception use (aOR: 0.99, [0.79, 1.24]), whereas rural adolescents had significantly higher use (aOR: 1.79, [1.35, 2.36]). Among sexually active respondents who were not using contraception, the rate of contraception counseling in non-city urban adolescents was 66.7%. In comparison, the city dwellers had higher rate of counseling (79.1%, aOR: 1.87; 95% CI: [1.09, 3.22]). Similarly, rural adolescents also had higher rate of counseling (81.5%, aOR: 2.37; 95% CI: [1.08, 5.19]). 

In short, rural residents were more likely to use effective contraception methods than their city and non-city urban counterparts. However, higher rates of contraception counseling among sexually active adolescents not using contraception in city and rural densities could suggest ineffective counseling in these groups. So there are differences in contraceptive use between rural and urban adolescents which warrant further study. And more studies are needed to understand how to more effectively increase contraception knowledge across all populations, for an ever-changing group of adolescents.

Electron Spin and Proton Spin in the Hydrogen and Hydrogen-Like Atomic Systems

Read full paper at: http://www.scirp.org/journal/PaperInformation.aspx?PaperID=52202#.VIj7tMnQrzE Author(s) Stanisław Olszewski * Affiliation(s) Institute of Physical Chemistry, Polish Academy of Sciences, Warsaw, Poland . ABSTRACT The mechanical angular momentum and magnetic moment of the electron and proton spin have been calculated semiclassically with the aid of the uncertainty principle for energy and time. The spin effects of both kinds of the elementary particles can be expressed in terms of similar formulae. The quantization of the spin motion has been done on the basis of the old quantum theory. It gives a quantum number n = 1/2 as the index of the spin state acceptable for both the electron and proton ...

ABSTRACT This paper is motivated by the concept of the signed k-domination problem and dedicated to the complexity of the problem on graphs. For any fixed nonnegative integer k, we show that the signed k-domination problem is NP-complete for doubly chordal graphs. For strongly chordal graphs and distance-hereditary graphs, we show that the signed k-domination problem can be solved in polynomial time. We also show that the problem is linear-time solvable for trees, interval graphs, and chord...
