Ewing's sarcoma is a rare tumor first discovered by James Ewing in 1921. It is more common in bone or skeletal component compared to soft tissue or extraosseous Ewing's sarcoma. Among soft tissue Ewing’s, spinal cord involvement is rarer with only nine cases reported. We report a case of nine-year-old Malay girl who presented with low back pain for two months following a fall with progressive neurological deficits of bilateral lower limb. Magnetic resonance imaging was suggestive of a well-defined margin of intradural extramedullary tumor. With nerve sheath tumor in mind, surgical excision with laminectomy L2-S1 was performed. Intraoperative finding was an extradural mass from L3-L5 with extension to bilateral neuroforamen. Histopathology report defined a round cell tumour of Ewing’s sarcoma from the mass.

Introduction: Adherence towards childhood immunization (completeness and timeliness), with consideration of age-dependent-seroconversion, is the basis for children protection. Despite high global and national immunization coverage, vaccine preventable diseases’ are rising. This study aimed to determine adherence (completeness and timeliness) towards different vaccines of childhood immunization and associated factors among mothers of under five children. Methods: Cross-sectional study design was conducted at a health clinic in Seremban. Total of 320 mothers of under five children attending child health clinic selected via systematic random sampling. Data collection was via validated self-administered questionnaires and proforma, analysed using SPSS version 22. Associations between categorical variables determined by chi-square tests. Results: Consented respondents were 314; resulting in response rate of 98.1%. Adherence (completeness) was 98.09% but only 56.5% - 97.1% of respondents adhered in terms of timeliness. Types of transportation was significantly associated with adherence (completeness), p=0.041. Employment status was significantly associated with adherence (timeliness) towards BCG (p=0.008), Hepatitis B dose one (p=0.018) and dose two (p=0.040) vaccines. Education level was significantly associated with adherence (timeliness) towards DTaP/IPV/HiB dose four (p=0.019). Maternal age and usage of government clinic were significantly associated with adherence (timeliness) of MMR dose one, p=0.030 and p=0.017 respectively. Conclusion: Adherence (completeness) was high but varying adherence towards vaccine timeliness. Transportation types associated with completeness. Employment status associated with BCG, first and second doses of Hepatitis B vaccines’ timeliness. Education level associated with fourth dose of DTaP/IPV/HiB. Maternal age and usage of government clinic associated with timeliness of first dose MMR.

Zamora MAL, Labao HC

Enferm Clin, 2020 02;30 Suppl 1:120-123.
PMID: 32115158 DOI: 10.1016/j.enfcli.2019.09.033

The caregiver's role in rearing a child with disability requires huge physical demands which may lead to development of musculoskeletal disorders such as low back pain (LBP). This study aims to determine the factors associated with low back pain among caregivers of children with disability. A quantitative, correlational research design was used. Data were gathered among caregivers of children with disabilities enrolled in a specialized educational and pediatric rehabilitation unit in Valenzuela City. A personal information sheet was used to gather relevant demographic data while Oswestry Disability Index (ODI) was used to measure low back pain and disability. Pearson's correlation and Chi-square were used to determine the relationship and association among demographic factors and low back pain and disability. Majority of the respondents are mothers (59.09%) caring for children with autism spectrum disorder (31.82%), married (68.18%), and living in an extended family (36.36%). Chi-squared revealed a statistically significant association between caregivers' gender (p=0.003), relationship to child (p=0.000), and marital status (p=0.000) to low back pain and disability. Results imply that married mothers who are the primary caregivers to children with disability are prone to develop low back pain and disability. Preventive and restorative physical interventions, such as caring rotation, is recommended. Future studies should focus on other factors such as psychosocial, physical, and emotional aspects of low back pain and disability among caregivers of children with disability.

Zalma AR, Safiah MY, Ajau D, Khairil Anuar MI

Health Promot Int, 2015 Sep;30(3):523-30.
PMID: 24150531 DOI: 10.1093/heapro/dat072

Interventions to counter the influence of television food advertising amongst children are important. Thus, reliable and valid instrument to assess its effect is needed. The objective of this study was to determine the reliability and validity of such a questionnaire. The questionnaire was administered twice on 32 primary schoolchildren aged 10-11 years in Selangor, Malaysia. The interval between the first and second administration was 2 weeks. Test-retest method was used to examine the reliability of the questionnaire. Intra-rater reliability was determined by kappa coefficient and internal consistency by Cronbach's alpha coefficient. Construct validity was evaluated using factor analysis. The test-retest correlation showed moderate-to-high reliability for all scores (r = 0.40*, p = 0.02 to r = 0.95**, p = 0.00), with one exception, consumption of fast foods (r = 0.24, p = 0.20). Kappa coefficient showed acceptable-to-strong intra-rater reliability (K = 0.40-0.92), except for two items under knowledge on television food advertising (K = 0.26 and K = 0.21) and one item under preference for healthier foods (K = 0.33). Cronbach's alpha coefficient indicated acceptable internal consistency for all scores (0.45-0.60). After deleting two items under Consumption of Commonly Advertised Food, the items showed moderate-to-high loading (0.52, 0.84, 0.42 and 0.42) with the Scree plot showing that there was only one factor. The Kaiser-Meyer-Olkin was 0.60, showing that the sample was adequate for factor analysis. The questionnaire on television food advertising is reliable and valid to assess the effect of media literacy education on television food advertising on schoolchildren.

Zalilah MS, Mirnalini K, Khor GL, Merlin A, Bahaman AS, Norimah K

Med J Malaysia, 2006 Mar;61(1):48-58.
PMID: 16708734 MyJurnal

The purpose of this study was to report on the estimates and distribution of body mass index in a sample of Malaysian adolescents. The study utilized a cross-sectional design and multi-stage random sampling of secondary schools to select 5 urban and 9 rural schools in Kedah and Penang. A total of 6555 male and female adolescents (11-15 years old) of Malay, Chinese and Indian ethnic groups were measured for weights and heights for body mass index calculation. Information on household demographic and socioeconomic were obtained from parents through self-administered questionnaires. Analyses of body mass index distribution by location, ethnicity, gender and age were conducted using Chi-square test of SPSS 11.5. More of the rural (12.1%) and urban (19.4%) adolescents were underweight and overweight, respectively. While in all ethnic, gender and age groups, rural adolescents were more likely to be underweight, more of the urban adolescents were overweight. The prevalence of underweight was highest among the Indians (19.2%) and lowest in Chinese (7.2%). The prevalence of overweight in the three ethnic groups was in the range of 18-19%. More male than female adolescents were underweight (15% vs 7.8%) and overweight (19.5% vs 16.7%). Consistent patterns were also observed across location, ethnic and age groups. As age increased, the prevalence of overweight decreased across the ethnic and gender groups. The reported findings can serve as current reference on body mass index distribution of Malaysian adolescents and a basis for future efforts in health and nutrition interventions for Malaysian children and adolescents.

Fulltext Food security and child nutritional status among Orang Asli (Temuan) households in Hulu Langat, Selangor

Zalilah MS, Tham BL

Med J Malaysia, 2002 Mar;57(1):36-50.
PMID: 14569716 MyJurnal

This study was conducted to determine the prevalence of household food insecurity and its potential risk factors and outcomes among the Orang Asli (Temuan) households. Socioeconomic, demographic and food security information of the households and anthropometric measurements and dietary intakes of preschoolers (n = 64) were obtained using a structured questionnaire. Food security was assessed using the Radimer/Cornell hunger and food insecurity instrument. Diet quality was based on 24 hour recall and analyzed according to the Malaysian RDA and Food Guide Pyramid. Majority of the households (82%) reported some kind of household food insecurity. The prevalence of significant underweight, stunting and wasting were 45.3%, 51.6% and 7.8%, respectively. Dietary intakes were less than 2/3 RDA levels for calories, calcium and iron. However, the intakes of protein, vitamin A, vitamin C and niacin exceeded the RDA and the sources for these nutrients were mainly rice, fish and green leafy vegetables. Among the five food groups, only the number of servings from cereals/cereal products/tubers group was achieved while that of the milk/diary products was the worst. Majority of the children (68.7%) had poor, 31.3% had fair and none with excellent diet quality. In general, diet quality and nutritional status of the children decreased as household food insecurity worsened. It is recommended that the nutritional problems of Orang Asli children be addressed through health, nutrition and economic programs and further studies should be carried out on determinants and consequences of household food insecurity.

Fulltext Parental perceptions of children's body shapes

Zalilah MS, Anida HA, Merlin A

Med J Malaysia, 2003 Dec;58(5):743-51.
PMID: 15190662 MyJurnal

The aim was to determine the differences in parents' perceptions of boys' and girls' body shapes and the explanations for the emphasis on body shape care of children. Subjects were low-income parents (n = 158) of preschoolers attending preschools in Kuala Lumpur, Malaysia. Parental perceptions of children's body shapes were assessed based on their rankings (scale of 1 to 7) of four attributes (ideal, healthy, fat and thin) for boy and girl figures. Parental responses to five questions on the importance of body shape were also obtained. Parental rankings of ideal and healthy body shapes were significantly lower for girls than boys (p < 0.001). However, mothers' and fathers' rankings of boys' and girls' body shapes were not significantly different. for both boys and girls, parental ratings for ideal body shape were significantly lower than for healthy body shape (p < 0.001). The majority of parents indicated that children's body shape is important for their future health, self enhancement, social interaction and career. With the increasing prevalence of body dissatisfaction among Malaysian children, these findings contribute to the understanding of parental roles in the development of body image and perhaps, in the etiology of body dissatisfaction among children.

Fulltext Micronutrients and its correlation with mental performance among schoolchildren in Bario, Sarawak: a preliminary study

Zaleha MI, Noor Hayaati AR, Mohd Rizam AR, Jamaludin M, Osman A

Med J Malaysia, 2003 Aug;58(3):309-19.
PMID: 14750369

Children who are born in a community with insufficient micronutrients, particularly iodine in remote rural areas are associated with low intellectual functions and mental retardation. The aim of this cross-sectional study is to determine the mental performance of the schoolchildren in Bario, a highland settlement of the Kelabit people in the district of Baram, Sarawak and to determine its correlation with the availability of iodine in the environment, as well as other micronutrients such as selenium, copper and manganese. A total of 25 schoolchildren in Bario age ranging from 7 to 12 years old participated in the study. Mental performance of the schoolchildren were tested using TONI-2 (Test of Nonverbal Intelligence--second edition), a cognitive ability measures with a response format which eliminates language and reduces motoric and cultural factors. The iodine levels from several wells, soils and salt found in Bario were determined using HPLC (software version 3.05.01) whilst serum levels of selenium, copper and manganese were measured using Graphite Furnace Atomic Absorption Spectrophotometer (GFAAS). The results showed that the median and mode scores of intelligence quotient for Bario were 82 and 75, respectively, whilst median and mode scores of intelligence percentile were 11.0 and 5.0, respectively. The maximum score achieved were at the average level with the quotient score between 90-110. It was found that salt produced from one of the wells in Bario contained high quantity of iodine. Based on standards established by the Trace Elements Laboratory, Roben Institute, University of Surrey, United Kingdom, schoolchildren in Bario are having sufficient blood levels of copper and a high selenium and manganese levels. Despite the remoteness of the study area, the schoolchildren in Bario, Sarawak showed higher mental performance compared to other isolated areas. This is probably correlated with the high micronutrients availability, particularly iodine, found naturally in Bario.

Zalbahar N, Najman J, McIntyre HD, Mamun A

Clin Obes, 2017 Aug;7(4):206-215.
PMID: 28557382 DOI: 10.1111/cob.12200

The purpose of this study was to examine the association of parental pre-pregnancy weight and body mass index (BMI) on offspring weight and BMI change from childhood to adulthood. We analysed BMI data from a subsample of parents (n = 1494) from the Mater-University of Queensland Study of Pregnancy cohort that started in the early 1980s in Brisbane, Australia: data were collected at pre-pregnancy and then also for offspring at 5, 14 and 21-year follow-ups. Multiple regression for continuous outcomes and multinomial regression for categorical outcomes were performed. A total of 14.7% of offspring experienced BMI change from normal at 5 years to overweight or obese (OW/OB) at 14 years, 15.3% of normal at 14 years to OW/OB at 21 years and 22.8% from normal at 5 years to OW/OB at 21 years. Overall, the strength of the association of parental BMI with offspring BMI was stronger as offspring become older. Pre-pregnancy parental BMI differentially impacts offspring OW/OB across the life course. For every unit increase in paternal and maternal BMI z-score, offspring BMI z-score increased, on average, by between 0.15% (kg m-2) and 0.24% (kg m-2) throughout all three stages of life when both parents were OW/OB; these associations were stronger than with one parent. Parental pre-pregnancy BMI and OW/OB is a strong predictor of offspring weight and BMI change from early life to adulthood.

Int J Environ Res Public Health, 2019 06 17;16(12).
PMID: 31213022 DOI: 10.3390/ijerph16122147

The validation of a new questionnaire is essential to improving its credibility in the assessment and collection of evidence. This study aimed to validate a newly developed infant and young child feeding questionnaire for child care providers (IYCF-CCPQ) to measure the knowledge, attitudes, and practices regarding infant and young child feeding among them. A cross-sectional study was conducted with 200 child care providers who were involved in handling children less than two years old in child care centers in the northeastern part of Peninsular Malaysia. The IYCF-CCPQ was self-administered and consists of three domains: Knowledge (104 items), attitude (90 items), and practice (42 items). The dichotomous-scale items in the knowledge domain were analyzed using a two-parameter logistic model of item response theory (2-PL IRT). The Likert-type-scale items in the attitude section were assessed using exploratory factor analysis (EFA). The items in the practice section were assessed descriptively. Internal consistency by marginal reliability was assessed in the knowledge domain, and Cronbach's alpha coefficient was used for the attitude domain. The marginal reliability values were 0.91 and 0.74 for the knowledge domains related to breastfeeding/formula feeding and complementary feeding, respectively, and the Cronbach's alpha values were 0.89 and 0.90 for the attitude domains related to breastfeeding/formula feeding and complementary feeding, respectively. The analysis showed good psychometric properties (discrimination, difficulty index, factor loading, and communalities) and good reliability. The IYCF-CCPQ is valid for use assessing the knowledge, attitudes, and practices among Malaysian child care providers regarding infant and young child feeding.

Zakiah I, Ashikin YN, Aisiah SM, Ismail HI

Southeast Asian J. Trop. Med. Public Health, 1995;26 Suppl 1:134-6.
PMID: 8629092

The Malaysian level of health care has greatly improved so that many of the infectious diseases are now under control. However, perinatal death or death due to unknown childhood diseases remains high (10.3%) being second on the list of causes of death amongst Malaysians. Could inborn metabolic diseases be the main cause of death among these children? Recently, with our success in the development of confirmatory techniques for amino acid disorders using high performance liquid chromatography (HPLC), we have examined 404 samples received from all over the country in 1993. Each specimen with abnormal findings from screening tests by one-dimensional thin layer chromatography was confirmed using HPLC. 41% had generalized aminoacidurias and 4.2% had maple syrup urine disease (MSUD). Patients were aged between 11 days to 6 years. Most of them were Malay males and presented with a history suggestive of MSUD. With this preliminary finding, further studies will be carried out in order to have an investigation and management protocol for the diseases and more importantly to formulate a strategy of screening for the country.

JUMMEC, 2018;21(2):38-44.
MyJurnal

Objective: The study was designed to determine the risk perception of the public population in Kota Kinabalu towards childhood immunisation.
Methodology: This was a cross-sectional study where self-administered questionnaires were distributed to the public in Kota Kinabalu. The respondents who consented were 18 years old and older. The illiterate persons and the foreigners were excluded. The calculated sample size was 400. Only 313 samples collected were suitable for analysis using SPSS v21.0.
Results: Fever, pain swelling and allergic reaction were correctly identified as risks of immunisation. Autism, mental retardation and even death could also result from vaccination. Of the total respondents, 76.7% agreed with the practice of childhood vaccination, 70.0% thought that childhood vaccinations were safe and effective and 58.1% felt that its benefit outweighed the risk. Other than that, 32.0% refused childhood vaccination from fear of its risks, and this fear was the main reason for the refusal of childhood vaccination. Age, marital status, race and income were the factors which influenced parental willingness to vaccinate their children (p<0.05).
Conclusions: Most participants understood the risks of childhood vaccination, but few agreed to the practice of childhood immunisation for herd immunity. Public health campaigns are needed, to increase the understanding and acceptance of childhood vaccination especially in the rural community.

Fulltext The prevalence of hypertension among Malaysian adults and its associated risk factors: data from Malaysian Community Salt Study (MyCoSS)

Zaki NAM, Ambak R, Othman F, Wong NI, Man CS, Morad MFA, et al.

J Health Popul Nutr, 2021 05 31;40(Suppl 1):8.
PMID: 34059165 DOI: 10.1186/s41043-021-00237-y

BACKGROUND: Hypertension is one of the most common risk factors for cardiovascular disease and leading cause of mortality globally. The aims of this study were to assess the prevalence of hypertension and its associated risk factors among Malaysian population using data from the Malaysian Community Salt Study (MyCoSS).
METHODS: This study was a cross-sectional study using multi-stage stratified sampling method. Data collection was carried out via face-to-face interview at the respondent's home from October 2017 until March 2018. A total of 1047 respondents aged 18 years and above completed the questionnaires and blood pressure measurement. A person who reported diagnosis of hypertension by a physician and had systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg on three readings was categorised as hypertensive. Risk factors of hypertension were analysed using multiple logistic regression.
RESULTS: The prevalence of hypertension in the present study was 49.39% (95% CI 44.27-54.51). There was no statistically significant difference in gender. Age, household income, BMI, and diabetes were significantly associated with hypertension. Hypertension found had inverse association with the level of education. Age was the strongest predictor of hypertension (35-44 years old; OR=2.39, 95% CI=1.39-4.09, 45-54 years old; OR=5.50, 95% CI=3.23-9.38, 55-64 years old OR=13.56, 95% CI=7.77-23.64 and 65 years old and above; OR=25.28, 95% CI=13.33-48.66). Those who had higher BMI more likely to be hypertensive as compared to respondents with normal weight (overweight, OR=1.84; 95% CI=1.18-2.86; obese, OR=4.29% CI=2.56-7.29).
CONCLUSION: The findings showed that hypertension is prevalent among adults in Malaysia. Those with older age, higher BMI, and diabetes are more likely to have hypertension. Efforts regarding lifestyle modification and education could be important in hypertension management and prevention.

PMID: 22690285 DOI: 10.3941/jrcr.v6i3.745

Neonatal onset multisystem inflammatory disease (NOMID) is a rare autoinflammatory disorder, which manifests early in infancy. We describe a case of a 10-year-old boy who has been unwell since infancy. He presented with urticarial rash, intermittent fever and hepatosplenomegaly followed by progressive arthropathy. His joint symptoms started at two years of age, which progressively involved multiple joints, resulting in bone and joint deformities. A series of joint radiographs demonstrated bizarre enlarging physeal mass with heterogenous calcification. Magnetic resonance imaging (MRI) of the involved right ankle and knee showed characteristic thickened and calcified physeal lesions, which enhanced post-gadolinium. This debilitating disease is also known to involve the central nervous system and eyes. This case report aims to highlight the conventional radiographic and magnetic resonance imaging (MRI) findings of this physeal abnormality in NOMID syndrome.

PMID: 22135590

We report a case of a 13-year-old boy who complained of progressive abdominal distension and symptoms of anaemia. Radiological investigations revealed that the child had a hypervascular tumour of the inferior vena cava (IVC). Unfortunately, the child presented with acute lower gastrointestinal bleed soon after the investigation. He underwent an urgent pre-operative embolisation, aimed to reduce the tumour vascularity. A total resection of the tumour, right nephrectomy, and partial duodenal resection were done within 24 hours post-embolisation. The child was stable postoperatively. The histopathological examination revealed chromogranin-positive paraganglioma originating from the IVC. We highlight the radiological findings of rare primary IVC paraganglioma and the role of embolisation prior to surgical removal of the tumour.

Four hundred and forty three teachers from eight ran-domly selected primary schools were enrolled in this study which was aimed at determining the knowledge regarding child abuse and neglect among primary school teachers in Kuala Lumpur. The areas that were examined included characteristics of child abusers and abused children. The results showed that the marital status of the teachers did not influence their level of knowledge and there was no significant difference between novice and senior teachers. The most impor-tant finding here was that knowledge regarding sexual and physical abuse was lacking in the teachers surveyed.

The impact of CYP2B6 polymorphisms on the interactions of efavirenz with lumefantrine: Implications for paediatric antimalarial therapy

Zakaria Z, Badhan RKS

Eur J Pharm Sci, 2018 Jul 01;119:90-101.
PMID: 29635009 DOI: 10.1016/j.ejps.2018.04.012

Lumefantrine is a widely used antimalarial in children in sub-Saharan Africa and is predominantly metabolised by CYP3A4. The concomitant use of lumefantrine with the antiretroviral efavirenz, which is metabolised by CYP2B6 and is an inducer of CYP3A4, increases the risk of lumefantrine failure and can result in an increased recrudescence rate in HIV-infected children. This is further confounded by CYP2B6 being highly polymorphic resulting in a 2-3 fold higher efavirenz plasma concentration in polymorphic subjects, which enhances the potential for an efavirenz-lumefantrine drug-drug interaction (DDI). This study developed a population-based PBPK model capable of predicting the impact of efavirenz-mediated DDIs on lumefantrine pharmacokinetics in African paediatric population groups, which also considered the polymorphic nature of CYP2B6. The validated model demonstrated a significant difference in lumefantrine target day 7 concentrations (Cd7) in the presence and absence of efavirenz and confirmed the capability of efavirenz to initiate this DDI. This was more apparent in the *6/*6 compared to *1/*1 population group and resulted in a significantly lower (P

Whole-Exome Sequencing of ETV6/RUNX1 in Four Childhood Acute Lymphoblastic Leukaemia Cases

Zakaria Z, Othman N, Ismail A, Kamaluddin NR, Esa E, Abdul Rahman EJ, et al.

Asian Pac J Cancer Prev, 2017 04 01;18(4):1169-1175.
PMID: 28548470

Background: ETV6/RUNX1 gene fusion is the most frequently seen chromosomal abnormality in childhood acute
lymphobastic leukamia (ALL). However, additional genetic changes are known to be required for the development of
this type of leukaemia. Therefore, we here aimed to assess the somatic mutational profile of four ALL cases carrying the
ETV6/RUNX1 fusion gene using whole-exome sequencing. Methods: DNA was isolated from bone marrow samples
using a QIAmp DNA Blood Mini kit and subsequently sequenced using the Illumina MiSeq system. Results: We
identified 12,960 to17,601 mutations in each sample, with a total of 16,466 somatic mutations in total. Some 15,533
variants were single nucleotide polymorphisms (SNPs), 129 were substitutions, 415 were insertions and 389 were
deletions. When taking into account the coding region and protein impact, 1,875 variants were synonymous and 1,956
were non-synonymous SNPs. Among non-synonymous SNPs, 1,862 were missense, 13 nonsense, 35 frameshifts, 11
nonstop, 3 misstart, 15 splices disrupt and 17 in-frame indels. A total of 86 variants were located in leukaemia-related
genes of which 32 variants were located in the coding regions of GLI2, SP140, GATA2, SMAD5, KMT2C, CDH17,
CDX2, FLT3, PML and MOV10L1. Conclusions: Detection and identification of secondary genetic alterations are
important in identifying new therapeutic targets and developing rationally designed treatment regimens with less
toxicity in ALL patients.

Fulltext Perceptions of Quality of Life during the Pandemic: A Case Study on B40 Single Mothers

Zakaria SM, Abdullah N, Md Akhir N, Amin AS, Mohd Shukry ANA, Abdul Rashid MR, et al.

Int J Environ Res Public Health, 2022 Sep 27;19(19).
PMID: 36231521 DOI: 10.3390/ijerph191912219

During the pandemic, the lives of B40 single mothers were severely affected, especially in terms of social, economic, and psychological factors. The reduction of income caused by the crisis has forced single mothers and their children to live frugally and without luxury. They also had to perform more than one job at a time during the pandemic to meet their children's needs. A qualitative study has been conducted to explore the perceptions of quality of life during the pandemic among B40 single mothers. Respondents were selected based on demographic characteristics established before the study. A focus group discussion has been conducted on ten (10) B40 single mothers in Balik Pulau, Penang. Single mothers were selected based on purposive sampling. They had to meet the inclusive criteria required to participate in the study, specifically: aged between 20 and 60 years old, belonged to the B40 income category, had children under 18 years old living together, and became single mothers due to divorce or death of husbands. The focused group discussion explored issues related to qualities of life during the pandemic. B40 single mothers expressed their concern about access to health facilities, security in residence, children's education, and economic stability. These areas of life quality have been significantly affected especially during Movement Control Order (MCO). In short, the quality of life of these single mothers has been significantly affected by the pandemic. Their vulnerability towards stress, anxiety, and depression have worsened due to financial issues. Besides the need for emotional and social support, this study found that these single mothers entail financial support.
