Screening for central precocious puberty by single basal Luteinizing Hormone levels

PURPOSE

To identify cut-off for basal LH levels and for pelvic ultrasound uterine and ovarian parameters indicating an Hypotalamic-Pituitary-Gonadal (HPG) axis activation as diagnostic of Central Precocious Puberty (CPP).

METHODS

248 girls referred for suspected precocious/early puberty who had undergone a GnRH stimulation test were enrolled and divided into three groups: Premature Idiopathic Thelarche (PIT), CPP, and Early Puberty (EA). For every patient basal serum Luteinising Hormone (LH) and Follicle Stimulating Hormone (FSH), basal LH/FSH ratio and pelvic ultrasonographic parameters were also collected. Through the use of Receiver Operating Curves (ROCs) the sensitivity (Se) and specificity (Sp) of basal LH, FSH, LH/FSH ratio and ultrasonographic parameters were evaluated at each level and Area Under the Curve (AUC) was measured.

RESULTS

Basal LH model ≥0.14 mIU/mL reached the highest predictability (90.6% and 78.2%, Se and Sp, respectively). Basal LH/FSH ratio ≥0.1 showed a sensitivity of 85.90% and a specificity of 78.14%, while basal FSH cut-off (≥2.36 mIU/mL) had the lowest predictability, with a less favourable sensitivity (71%) and specificity (70.5%). Cut-off point for uterine length as 35 mm, (83.5% and 42.9% of Se and Sp, respectively) was calculated. For ovarian volumes, ROC curves showed very low sensitivity and specificity.

CONCLUSION

A single basal LH measurement under the cut-off limit may be adequate to exclude an HPG axis activation as CPP.

The effect of GnRH analog treatment on BMI in children treated for precocious puberty: a systematic review and meta-analysis

INTRODUCTION

The purpose of the present meta-analysis was to systematically evaluate the effect of GnRHa treatment on the BMI of children with precocious puberty after GnRHa treatment as compared to before, and to analyze the effect of GnRHa treatment on the body composition of children with precocious puberty at different BMIs by classifying into normal body mass, overweight, and obese groups according to BMI at the time of initial diagnosis.

CONTENT

A meta-analysis was performed using Stata 12.0 software by searching PubMed, Embase, Web of Science, Cochrane Library, China National Knowledge Infrastructure (CNKI), Chinese Scientific Journal Database (VIP database), and Wan fang database for relevant literature on standard deviation score of body mass index (BMI-SDS) after GnRHa treatment as compared to before in children with precocious puberty.

SUMMARY

A total of eight studies were included with a total sample size of 715 cases, and the results of meta-analysis showed that BMI-SDS increased in children with precocious puberty after GnRHa treatment as compared to before starting [(weighted mean difference (WMD)=0.23, 95 % CI: 0.14-0.33, p=0.000)] and also increased in children with normal body mass [(WMD=0.37, 95 % CI: 0.28-0.46, p=0.000)], and there was no significant change in BMI-SDS in children in the overweight or obese group [(WMD=0.01, 95 % CI: -0.08-0.10, p=0.775)].

OUTLOOK

Overall, there was an observed increase in BMI-SDS at the conclusion of GnRHa treatment in children with precocious puberty. Additionally, it was found that the effect of GnRHa treatment on body composition varied among children with different BMI status. Clinicians should emphasize the promotion of a healthy lifestyle and personalized dietary management for children.

The mediating effects of parenting style on the relationship between parental stress and behavioral problems in girls with precocious puberty in Korea: a cross-sectional study

BACKGROUND

This study aimed to examine the mediating effects of parenting style on the relationship between parental stress and behavioral problems of girls with precocious puberty.

METHODS

This cross-sectional study analyzed a convenience sample of 200 mothers of girls with precocious puberty at a university hospital located in a metropolitan area. The Parental Stress measurement, Parents as Social Context Questionnaire, and Korean version Child Behavior Checklist (K-CBCL) 6-18 were measured via self-report questionnaires. Descriptive, t-test, Pearson correlation, and bootstrapping analyses were used to analyze the data.

RESULTS

Negative parenting styles had a full mediating effect on the relationship between parental stress and internalizing and externalizing behavioral problems.

CONCLUSIONS

Care plans for parents of girls with precocious puberty should be designed and applied in health care settings to reduce internalizing and externalizing behavioral problems by decreasing negative parenting styles.

Perception of precocious puberty among school-aged children in South Korea with the experience of treatment for precocious puberty: a Q methodological approach

PURPOSE

This study aimed to investigate the perceptions of precocious puberty and elucidate the distinct characteristics of each type of perception related to precocious puberty among school-aged children who had undergone treatment for the condition.

METHODS

This study applied the Q methodology to identify and classify the perceptions of precocious puberty among school-aged children who had undergone treatment for the condition. The analysis involved 34 questions from the Q sample and data from 35 individuals in the P sample, using the PC-QUANL Program for analysis.

RESULTS

The perceptions of precocious puberty among school-aged children who had undergone precocious puberty treatment were classified into the following four types: "shyness - passive self-management," "resentment - suppression," "anxiety - fear," and "adaptation - acceptance."

CONCLUSION

This study investigated the experiences and perceptions of children who have undergone treatment for precocious puberty. Through the identification of four types of perceptions, we can see that there is a need to develop an intervention program for nursing that is tailored to the specific type of precocious puberty.

Earlier Age at Menarche Is Associated with Body Fat and Negative Body Image in Adult Life

Earlier age at menarche is one of the well-documented antecedents of a range of adverse health effects in adulthood including obesity and psychopathological effects. Yet, few researchers have examined the potential association of menarcheal age with body fat distribution, self-perception, and body image. We retrospectively tested a sample (N = 392) of adult women (18-80 years) to examine the associations of age at menarche with body composition and body image indices. Analyses of covariance and multivariable logistic and linear regression were fitted adjusting for age, physical activity level, smoking, and alcohol consumption. Further adjustment was made for body mass index (BMI) and percentage of fat mass. Earlier age at menarche was associated with slightly increased odds of higher BMI and abdominal fat percentage; of note is the positive correlation with lower body composition indices including hip and calf circumferences/skinfolds. Additionally, earlier age at menarche was associated with higher scores in the negative body image scales, namely overweight preoccupation and self-classified weight, whereas lower risks were found for higher scores in the positive body image scales, namely appearance evaluation and body area satisfaction scales. These findings remained significant after correcting for body fat percentage. The present results showed positive associations for earlier age at menarche with gross indices of obesity with the associations mainly confined to distribution of body fat in the lower part of the body, whereas an increased risk of negative body image was also found. Future research could refine our understanding of the biological and psychological mechanisms underlying these associations.

Psychosocial adaptation to precocious puberty: A nursing support program

PROBLEM

This study aimed to determine the effects of a nursing support program (NSP) based on the Roy Adaptation Model on the psychosocial adaptation of girls with precocious puberty and their mothers.

METHODS

This study adopted a pre-post design. It included 26 girls diagnosed with precocious puberty and their mothers. Data were collected using a Demographic Information Form; the Child Behavior Checklist for Ages 6-18; and the Depression, Anxiety, and Stress Scale. Participants were then enrolled in a NSP based on the Roy Adaptation Model. The same measures were administered at the end of the support program to the participants.

FINDINGS

It was determined that at the beginning of the program, approximately one-third of the mothers had depression, 15% anxiety, and approximately 20% experienced stress. Mothers' anxiety and stress levels and girls' anxiety/depression and total problem scores significantly decreased after the NSP.

CONCLUSIONS

The NSP designed for this study positively affected the psychosocial problems of girls with precocious puberty and their mothers.

Association between illegal use of substances and suicidal behavior in school students: An integrative review of empirical data

PURPOSE

Investigation of the association between type of suicidal behavior and type and frequency of illegal use of substances (IUS) among school students (aged between 12 and 18 years), with a focus on gender differences.

DESIGN AND METHODS

A systematic review in PubMed, CINAHL, PsychINFO, and Scopus was performed. Identified articles were published between 2007 and 2018.

RESULTS

Twenty empirical studies confirmed the association between IUS and suicidality, strongly differentiated between males and females, highlighting the importance of gender-specific mediating factors.

CONCLUSIONS

Mental health nurses need to document gender factors, frequency, and motivation of IUS when screening adolescents experiencing suicidal behavior and IUS.
