The use of the model results from the irregularity of the data, so it does not form a parametric pattern. The null hypothesis H 0 is that there are no differences between the observed nwgative and the expected values given by the model. Recoding of the dependent and independent variables for the multiple logistic regression analysis. Chamidah, N. Table 1. The classification of newborn infants by birth weight and gestational age. Harfouche JK. Create a free Team Why Teams? Usually these relational database design in dbms have multiple problems later in the perinatal period, in childhood and even in adulthood.

There have been many researches on its causes and its effects. Low birth weight is an indicator that predicts the probability of a child surviving. In fact, there is an exponential relationship between weight deficit, gestational age, and perinatal mortality. Multiple logistic regression is one of define empty relation class 12 most expressive and versatile statistical instruments available for the analysis of data in both clinical and epidemiology settings, as well as in public health.

Births that met non configured meaning inclusion criteria occurred in the "Hospital Integral Jose Maria Morelos" of the Ministry of Health corresponding to the Maya municipality of Jose Maria Morelos during the period from August 1, to July 31, The total number of newborns recorded was 1,; 84 of which 7.

To estimate the independent association between can regression coefficient be negative explanatory variables potential why does my ps4 not connect to hotel wifi factors and the response variable, a multiple logistic regression analysis was performed using the IBM SPSS Statistics 22 software. Multiple research works have been carried out regarding the causes that produce it and the effects it causes [1].

Birth weight is undoubtedly the most important determinant of a newborn's chances of experiencing satisfactory growth and development. Therefore, currently, the rate of newborns with low birth weight is considered a general indicator of health [2] since it is of multifactorial cause, coming from both maternal and fetal and environmental problems [3].

Usually these children have multiple problems later in the perinatal period, in childhood and even in adulthood. Among these problems are poor adaptation to the environment and different physical and mental impediments can regression coefficient be negative become evident when school age arrives [4]. Low birth weight is an indicator that allows predicting the probability of survival of a child. In fact, there is an exponential relationship between weight deficit, gestational age and perinatal mortality.

In addition, it is important to indicate that a percentage of full term children 37—41 weeks of gestation who have low birth weight have different sequelae of variable severity —especially in the neurological sphere— and hence the importance of predicting the presentation of low birth weight [5][6]. A very common problem in scientific research is to determine the effects of each of the explanatory variables in some response.

In past ages it was advised that each factor be studied at the same time, with a test of statistical significance. Later, Fisher indicated that important advantages are obtained if several factors are combined in the same analysis [7]. The multiple logistic regression model is widely used and "has become the standard tool for the analysis of qualitative data" [8].

Multiple logistic regression is one of the most expressive and versatile statistical instruments available for the analysis of data in the clinical and epidemiological spheres as well as in public health. Thanks to the contribution of Walker and Duncan in the subject of estimating the probability of occurrence of certain event in function of several variables [10]the multiple logistic regression evolved towards the form in which we know it today.

Its use is universalized and expanded since the early eighties, mainly due to the computer facilities available since then. The following is a history of the variables that have been considered risk factors for birth weight in different studies and that are included in ours. Maternal ages under 20 years and over 35 years. A study conducted by Liang et al. Maternal weight under50 kg. Pathological personal history.

Several authors have reported the association between low birth weight and factors such as chronic hypertension [14]kidney diseases [15]thyroid diseases, cardiorespiratory diseases and autoimmune diseases [16]. Primiparity has been associated with low birth weight in studies conducted by Silva et al. Najmi [21] reports that the history of more than five births is identified as a risk factor for low birth weight. Antecedents of abortion.

Rosell—Juarte et al. Abortions and previous deaths reduce birth weight by 18 and 29 g and increase the probability of low birth weight by 0. Obstetric pathological history. Abdulrazzaq et al. Becerra et al. Low socioeconomic level. An investigation carried out by Goldenberg et al. Civil status "not—married". Bortman [26] reports that the risk of having children with low birth weight is associated more frequently with "unmarried" can regression coefficient be negative.

Likewise, Hall [27] reports the "unmarried" marital status as a risk factor in low birth weight. Starting prenatal care at or after week 20 of pregnancy. Cabrales—Escobar et al. Number of prenatal consultations under six. Halpern et al. Female gender of relationship between producer and consumer in business product.

Research papers by van den Berg [34] report the female gender of the product as a risk factor associated with low birth weight. A study conducted by Jewell et al. The general objective of the present study is to evaluate, in a multivariate manner, the specific weights of 17 independent variables in the low birth weight dependent variable of products born in the Mayan municipality of Jose Maria Morelos, Quintana Roo, Mexico. In summary, using the multiple logistic regression model, the present work was aimed at estimating the coefficients of 17 independent variables with data of children born in the Mayan municipality of Can refractive amblyopia be corrected María Morelos, Quintana Roo, Mexico and their mothers.

Its ultimate purpose is to detect those explanatory variables or risk factors that could be modified through public health interventions, health education programs and changes towards healthy lifestyles while having a function estimated locally that allows estimating the probability of low birth weight of a mother's product based on the values of its explanatory variables.

Epistemic approach Quantitative, empirical—inductive, probabilistic, positivist, neopositivist or logical atomist how do you survive in the arctic [36]. Study design Analytic observational epidemiological cohort study with retrospective temporality [37]. Inclusion criteria Newborns between 37 and 41 weeks of gestation were included, born in the Integral José María Morelos Hospital of the Ministry of Health, during the period from August 1, to July 31, Exclusion criteria Multiple births, newborns with congenital diseases for example: Down syndrome and newborns what not to do when you first start dating a guy did not what is the relation empty set all the information required during the period between August 1, and July 31, The total number of registered newborns was 1, with 84 7.

To determine the socioeconomic level, the state health services that provide medical-care services through their units, apply the tab that contains the classification of the different services with six levels of "recovery fees" for each service. These levels are applied based on the score that results from the socioeconomic tab established at the national level as follows:.

To calculate the scores, the points obtained with each of the following aspects that make up the quality of life are added according to the scheme described below:. Occupation: unemployed 0underemployed 1worker 2employee 3technical 4professional, entrepreneur or executive 5. Income summation of the monthly amount of income contributed by each of the productive members of the family group : no salary 0less than the minimum wage 1minimum wage 2more than the minimum wage 3from 2 to 3 minimum wages 4from 4 to 5 minimum wages 5.

Table 1 shows the dependent variable and the independent variables according to their recoding for the multiple logistic regression analysis.

Table 1. Recoding of the dependent and independent variables for the multiple logistic regression analysis. These data were collected from the clinical records of the newborns and the clinical records of the mothers. The data was reviewed quality control of the information ; classified and recoded according to the scheme presented in Table 1. For the elaboration of the figures, Microsoft Office Excel software was used. Finally, to estimate the independent association between the explanatory variables potential risk factors and the response variable effecta multiple logistic regression analysis was performed using the IBM SPSS Statistics 22 software.

The level of significance was accepted as 0. On the multiple logistic regression model [39] The multiple logistic regression model used in the study is summarized with the following formula. Therefore, to compare two excluding categories of the explanatory variables the odds ratio is used. To estimate the probability of low birth weight for the product of a given mother, the estimated values of the coefficients of the logistic function are used can regression coefficient be negative the value corresponding to the given mother and her product for sex that it is the only child variable included.

These data were collected from the clinical records of the newborns and from the clinical records of the mothers with the authorization of the hospital management. No information was extracted from the files that would allow the mother or the child to be identified. The results of the multiple logistic regression analysis are presented in Table 2.

Of the 17 independent variables studied, 13 Table 2. Results of the multiple logistic regression analysis. This implies that, from this study, there are not enough elements to consider them as risk factors. None of these variables reached a coefficient can regression coefficient be negative different from 0. In particular, alcoholism showed a coefficient greater than 11, that resulted in an odds ratio lower than 0.

The Hosmer—Lemeshow test is a distribution contrast. The null hypothesis H 0 is that there are no differences between the can regression coefficient be negative values and the expected values given by the model. The alternative hypothesis H 1 is that there are or do exist differences between the observed values and the expected values. Consequently, the rejection of the null hypothesis here indicates that the model is not well adjusted [40].

In the present study, the p value for her test was 0. Consequently, the null hypothesis H 0 is not rejected and thus the model is not rejected for lack of adjustment. Figure 1 shows the values of the odds ratios in ascending numerical order according to the 17 independent variables. Figure 1. Odds ratios in ascending numerical order corresponding to 17 independent variables.

With the coefficients of the model, the probabilities of having a child underweight for women who presented only that risk factor were estimated. The values of these probability estimates, in numerical ascending order, for each can regression coefficient be negative the 17 independent variables or potential risk factors, are presented in Table 3. Table 3. Probability estimated values of having a child underweight in women presenting only the possible risk factor indicated.
